System parameters of three short-period cataclysmic variable stars

J. F. Wild et al.

Summary: Using photometric ULTRACAM observations, the study models the primary eclipse light curves of three new short-period cataclysmic variables (CVs) to extract the orbital separation, masses, and radii of their component stars. The results show that the new systems are close to the empirical evolutionary sequence, and further detailed CV evolutionary models are needed for quantitative conclusions in the future.

Measuring the mass of the black widow PSR J1555-2908

M. R. Kennedy et al.

Summary: Accurate measurement of neutron star masses is crucial for testing binary evolution models and constraining the neutron star equation of state. This paper presents a new method for measuring the radial velocity of the companion star using the binary synthesis code ICARUS. Applied to the black widow pulsar PSR J1555-2908, the method estimates the radial velocity and binary inclination, leading to the determination of the neutron star and companion star masses.

Characterizing eclipsing white dwarf M dwarf binaries from multiband eclipse photometry

Alex J. Brown et al.

Summary: With the prevalence of wide-field, time-domain photometric sky surveys, the number of eclipsing white dwarf (WD) systems being discovered is increasing dramatically. An efficient method to follow these up will be key to determining any population trends and finding any particularly interesting examples.

Incremental Fermi Large Area Telescope Fourth Source Catalog

S. Abdollahi et al.

Summary: An incremental version (4FGL-DR3) of the fourth Fermi Large Area Telescope (LAT) catalog of gamma-ray sources is presented, which contains 6658 sources based on the first 12 years of science data. The analysis improves on the previous catalog by introducing better spectral parameterization for pulsars and extending the spectral points to 1 TeV. Updates are made to the spectral parameters, spectral energy distributions, and associations for all sources.

Einstein@Home discovery of the gamma-ray millisecond pulsar PSR J2039-5617 confirms its predicted redback nature

C. J. Clark et al.

Summary: The study identified a 'redback' millisecond pulsar binary system through the detection of optical and X-ray sources, and confirmed it as a binary MSP through a targeted gamma-ray pulsation search. The research also revealed significant variations in the orbital period of the companion star and the pulsed flux.

Discovery and modelling of broad-scale plasma lensing in black-widow pulsar J2051-0827

F. X. Lin et al.

Summary: This study reports on the bright observation of PSR J2051 - 0827 during a regular monitoring campaign of black-widow pulsar systems, showing interesting variations in flux density, dispersion measure (DM), and scattering strength. By investigating the causal link between DM and lensing, the flux density variations can be directly predicted, which can be applied to study the dynamics of other eclipsing systems and explore the physical nature of scintillation and lensing in the ionized interstellar medium in the future.

Optical photometry of two transitional millisecond pulsars in the radio pulsar state

J. G. Stringer et al.

Summary: ULTRACAM multiband optical photometry of two transitional millisecond pulsars (tMSPs), PSR J1023+0038 and PSR J1227-4853, reveals significant asymmetry in the light curves around the flux maxima, indicating an asymmetric source of heating in the system. Modelling shows that companion stars in both tMSPs have underfilled Roche lobes, contradicting the expected rapid filling of Roche lobes in these systems. Future research is suggested to further investigate the role of filling factor in the tMSP cycle.

HiPERCAM: a quintuple-beam, high-speed optical imager on the 10.4-m Gran Telescopio Canarias

V. S. Dhillon et al.

Summary: HiPERCAM is a portable quintuple-beam optical imager that can record images simultaneously with its five CCD cameras, allowing for both deep long-exposure imaging and high-speed imaging. Utilizing frame-transfer devices cooled thermo-electrically, it can achieve detections of astronomical sources at high precision. By combining HiPERCAM with the world's largest optical telescope, it can enhance the effective field of view and achieve detections of astronomical sources with high limits.

Roger W. Romani et al.

Summary: The Keck telescope spectrophotometry of the companion of PSR J1810+1744 reveals the presence of gravity darkening and near-filling of the Roche lobe, leading to an accurate determination of the neutron star mass with implications for the dense-matter equation of state.
