1RXS J174320.1-042953: another polar with a red-shifted absorption component in emission line wings
Diego H. González-Buitrago, Ma. T. García-Díaz, Sergey Zharikov +5
We present the results of a spectroscopic and multi-band photometric study of the magnetic cataclysmic variable 1RXS J174320.1-042953. Multi-band photometry confirms a periodic mod…
A Comprehensive Study of the Long-Period Cataclysmic Variable V630 Cassiopeiae
Ivan Mora Zamora, Gagik Tovmassian, Juan Echevarria +1
We present a comprehensive review of V630 Cassiopeiae, which is a very long-period cataclysmic variable. Based on new observations combining spectroscopy and high-resolution photom…
Evolution of a long-period Cataclysmic Variable from the viewpoint of the donor star: the case of SDSS J085210.48+783246.6
G. Tovmassian, D. Belloni, I. Mora Zamora +8
Cataclysmic variables were long considered to be close binaries consisting of a white dwarf and a Roche-lobe-filling, near-zero-age main-sequence (ZAMS) red or brown dwarf. Recent…
Chasing Gamma-Ray Signals from Binary Neutron Star Coalescences with the Cherenkov Telescope Array: Prospects and Observing Strategies
S. Abe, J. Abhir, A. Abhishek +457
The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…
The evolutionary history of ultra-compact accreting binaries. I. Chemical abundances and formation channel of the eclipsing AM CVn system ZTF J225237.05-051917.4 from HST spectroscopy
W. Yu, A. F. Pala, T. Kupfer +33
AM Canum Venaticorum (AM CVn) stars are ultra-compact binary systems composed of a white dwarf (WD) primary accreting from a H-deficient donor. They are important as potential prog…
Revisiting the extremely long-period cataclysmic variables V479 Andromedae and V1082 Sagitarii
Gagik Tovmassian, Diogo Belloni, Anna F. Pala +56
The overwhelming majority of CVs have orbital periods shorter than 10 hr. However, a few have much longer periods, and their formation and existence pose challenges for the CV evol…
Double White Dwarf Binaries in SDSS-V DR19 : The discovery of a rare DA+DQ white dwarf binary with 31 hour orbital period
Gautham Adamane Pallathadka, Vedant Chandra, Boris T. Gansicke +13
Binaries of two white dwarfs (WDs) are an important class of astrophysical objects that are theorized to lead to Type Ia supernovae and are also used to gain insight into complex p…
A targeted search for binary white dwarf pulsars using Gaia and WISE
Ingrid Pelisoli, T. R. Marsh, G. Tovmassian +24
After its discovery in 2016, the white dwarf binary AR Scorpii (AR Sco) remained for several years the only white dwarf system to show pulsed radio emission associated with a fast-…
The White Dwarf Binary Pathways Survey IV: Three close white dwarf binaries with G-type secondary stars
M. S. Hernandez, M. R. Schreiber, S. G. Parsons +12
Constraints from surveys of post common envelope binaries (PCEBs) consisting of a white dwarf plus an M-dwarf companion have led to significant progress in our understanding of the…
From outburst to quiescence: spectroscopic evolution of V1838 Aql imbedded in a bow-shock nebula
J. V. Hernández Santisteban, J. Echevarría, S. Zharikov +15
We analyse new optical spectroscopic, direct-image and X-ray observations of the recently discovered a high proper motion cataclysmic variable V1838 Aql. The data were obtained dur…
An XMM-Newton Spectral and Timing Study of IGR J16207-5129: An Obscured and Non-Pulsating HMXB
John A. Tomsick, Sylvain Chaty, Jerome Rodriguez +3
We report on a 12 hr XMM-Newton observation of the supergiant High-Mass X-ray Binary IGR J16207-5129. This is only the second soft X-ray (0.4-15 keV, in this case) study of the sou…
