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…
FQ Circini: An Ordinary Nova with a High-mass B1 V(n)(e) Companion Whose Decretion Disk Transfers Mass to the White Dwarf via Roche-Lobe Overflow
Bradley E. Schaefer, Andrew Pearce, Tom Love +4
FQ Cir was an ordinary fast He/N classical nova, peaking at =10.9. The pre-eruption and post-eruption counterpart was at =14.0, making the smallest known classical nova ampli…
Orbital Period Changes of Recurrent Nova U Scorpii Demonstrate that M=26M and Is Not a Type Ia Supernova Progenitor
Bradley E. Schaefer, Gordon Myers
Recurrent nova U Scorpii (U Sco) is one of the prototypes for a Type Ia supernova progenitor. The logic is that the white dwarf is near the Chandrasekhar mass and gas is accumulati…
A transiting hot Jupiter with two outer siblings orbiting an intermediate-mass post main-sequence star
Y. Reinarz, M. I. Jones, R. Brahm +15
Exoplanetary systems with multiple giant planets present an opportunity to understand planet formation, migration processes, and long-term system-wide dynamical interactions. In pa…
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…
Studying the black widow pulsars PSR J03120921 and PSR J16273219 in the optical and X-rays
A. V. Bobakov, A. Kirichenko, S. V. Zharikov +4
Context. PSR J03120921 and PSR J16273219 are black widow pulsars with orbital periods of 2.34 and 3.98 hours. They were recently detected in the radio and -rays. Aims. Our…
