Evidence for Multiple Shocks from the γ-Ray Emission of RS Ophiuchi

Rebecca Diesing et al.

Summary: In August 2021, the Fermi Large Area Telescope, H.E.S.S., and MAGIC detected GeV and TeV gamma-ray emission from a recurrent nova RS Ophiuchi, marking the first observation of very high-energy gamma-rays from a nova and providing new insights into particle acceleration. In this study, a detailed multi-zone modeling was performed to analyze RS Ophiuchi's 2021 outburst, incorporating a consistent approach to particle acceleration and magnetic field amplification. The results challenge previous findings by demonstrating that a single shock cannot account for both the GeV and TeV emissions, prompting the proposal of a model involving multiple shocks to explain the observed gamma-ray spectrum and temporal evolution. The presence of distinct velocity components in the nova's optical spectrum during the early days of the outburst supports the idea of multiple shocks, possibly due to the density variation of the external circumbinary medium or internal collisions within the white dwarf ejecta.

The multiwavelength view of shocks in the fastest nova V1674 Her

K. Sokolovsky et al.

Summary: V1674 Her is the fastest nova ever recorded that challenges our understanding of shock formation in novae. Through coordinated observations in different wavelengths, we found that the emission from V1674 Her can be explained by thermal and synchrotron radiation. Short-lived gamma-ray emission was detected in the 0.1-100 GeV range within 18 hours after the eruption of the nova began.

High-resolution X-ray spectra of RS Ophiuchi (2006 and 2021): Revealing the cause of SSS variability

J. -u. Ness et al.

Summary: The 2021 recurrent symbiotic nova RS Oph exploded on August 9, marking the seventh confirmed recorded outburst since 1898. A comparison between the 2006 and 2021 outbursts reveals similar behavior during the early shock phase but significant differences during the super-soft source (SSS) phase. By studying the spectra and observing the absorption, the authors aim to understand the emission and absorption mechanisms of the nova.

The High-resolution Soft X-Ray Spectrum of Nova Delphini 2013

Johon Milla et al.

Summary: We present the high-resolution soft X-ray spectrum of Nova Delphini 2013, obtained using the Low Energy Transmission Grating Spectrometer on the Chandra X-ray Observatory. The spectra taken 87 and 114 days after the nova eruption show clear spectral evolution. We detected both the photospheric emission spectrum of the hot white dwarf and the absorption spectrum of a shell of highly ionized gas, indicating thermonuclear fusion by the CNO cycle.

The super-soft source phase of the recurrent nova V3890 Sgr

J-U Ness et al.

Summary: In this study, the authors analyze the observations of the recurrent symbiotic nova V3890 Sgr and identify various variations in the X-ray emissions. They propose possible explanations for the observed variability and suggest that the constant bolometric luminosity concept can still be maintained.

The 2021 outburst of the recurrent nova RS Ophiuchi observed in X-rays by the Neil Gehrels Swift Observatory: a comparative study

K. L. Page et al.

Summary: This study investigates the extensive X-ray data sets of the recurrent nova RS Oph between 2006 and 2021, as well as limited data from 1985. The study finds that the hard X-rays following the last two eruptions are similar, but the early supersoft source in 2021 is less variable and fainter compared to 2006. However, a quasi-periodic oscillation consistent with the 2006 data is observed in the 0.3-1 keV light curves from 2021. The X-ray spectra from 2021 are featureless, while the 2006 spectra show evidence of superimposed ionized absorption edges.

Proton acceleration in thermonuclear nova explosions revealed by gamma rays

V. A. Acciari et al.

Summary: Classical novae are binary star systems where material from a companion star is accreted onto a white dwarf, leading to a thermonuclear explosion and the ejection of accumulated matter. In this study, the detection of gamma rays from the 2021 outburst of RS Ophiuchi allowed for a better understanding of the acceleration of protons to high energies and the creation of cosmic ray bubbles.

NICER Monitoring of Supersoft X-Ray Sources

M. Orio et al.

Summary: By monitoring four supersoft sources, we observed short-period modulations in two persistent supersoft X-ray sources, while they were absent in the recent novae. We suggest that these modulations occur on the surface of the white dwarf. The pulsations in CAL 83 were almost unchanged, while V1674 Her consistently showed large amplitude pulsations.

Fermi LAT Gamma-ray Detection of the Recurrent Nova RS Ophiuchi during its 2021 Outburst

C. C. Cheung et al.

Summary: This paper reports the Fermi LAT gamma-ray detection of the 2021 outburst of the symbiotic recurrent nova RS Ophiuchi. The LAT spectra from 50 MeV to similar to 2-23 GeV are consistent with pi(0)-decay emission from shocks in the ejecta. The LAT light curve shows a fast rise to its peak flux and exhibits a power-law decline, with evidence of a localized shock-acceleration event. Comparisons between gamma-ray and optical luminosities suggest attenuation of gamma rays at the earliest stages of the shock development.

Study of 2021 outburst of the recurrent nova RS Ophiuchi: Photoionization and morphokinematic modelling

Ruchi Pandey et al.

Summary: We observed the evolution of the optical spectra of the RS Ophiuchi (RS Oph) outburst in 2021 for about a month. The spectral evolution is similar to previous outbursts, with prominent P Cygni profiles in the early spectra. The expanding shocked material into the red giant companion's winds is believed to be the cause of the narrowing and sharpening of the emission lines. The study also derived physical and chemical parameters of the system using the photoionization code CLOUDY.

Radio interferometric imaging of RS Oph bipolar ejecta for the 2021 nova outburst

U. Munari et al.

Summary: The recurrent nova and symbiotic binary RS Oph experienced its eighth outburst in August 2021, showing a radio structure remarkably similar to that observed after the 2006 eruption. By comparing with optical spectra, the expansion speed of the lobes and the orbital inclination of the binary were determined. The article also discusses the role of density enhancement on the orbital plane and the formation of triple-peaked profiles.

Binary Interaction Dominates Mass Ejection in Classical Novae

Ken J. Shen et al.

Summary: Recent observations suggest that our current understanding of mass loss in classical novae is incomplete, prompting a new theoretical investigation into the physical processes responsible for nova mass ejection. The study shows that white dwarfs can successfully launch optically thick winds under certain conditions, but these winds are influenced by the binary companion, leading to different modes of outflow acceleration.

Estimating Distances from Parallaxes. V. Geometric and Photogeometric Distances to 1.47 Billion Stars in Gaia Early Data Release 3

C. A. L. Bailer-Jones et al.

Summary: Stellar distances are essential in astrophysics, and the publication of 1.47 billion stellar parallaxes from Gaia significantly contributes to this field. Despite challenges with faint or distant stars, a probabilistic approach using a three-dimensional model of the Galaxy has been developed to estimate geometric and photogeometric distances. Photogeometric estimates generally show higher accuracy and precision compared to geometric distances, especially for stars with poor parallaxes, and are provided in a publicly available catalog.

New Insights into Classical Novae

Laura Chomiuk et al.

Summary: Classical novae are nonterminal, thermonuclear eruptions on white dwarfs in binary systems. The recent discovery of GeV gamma rays from Galactic novae has shown the complexity of novae and their importance as laboratories for studying shocks and particle acceleration. The mass ejection processes of novae are poorly understood, leading to the production of gamma-ray-producing shocks internal to the nova ejecta which significantly contribute to the bolometric luminosity of novae.

AstroSat soft X-ray observations of the symbiotic recurrent nova V3890 Sgr during its 2019 outburst

K. P. Singh et al.

Summary: Two long observations were taken of the third recorded outburst of the symbiotic recurrent nova V3890 Sgr using the AstroSat Soft X-ray Telescope. The observations revealed unstable and variable behavior of the shock component and supersoft source (SSS) emission. The second observation showed an even brighter but still highly variable SSS component compared to the first observation.
