The magnetic system SMSS J1606-1000 as a period bouncer
Adela Kawka, Stephane Vennes, Lilia Ferrario +7
We report the discovery of a rare close binary system, SMSS J160639.78-100010.7, comprised of a magnetic white dwarf with a field of about 30 MG and a brown dwarf. We measured an o…
The MAVERIC Survey: Simultaneous Chandra and VLA observations of the transitional millisecond pulsar candidate NGC 6652B
Alessandro Paduano, Arash Bahramian, James C. A. Miller-Jones +12
Transitional millisecond pulsars are millisecond pulsars that switch between a rotation-powered millisecond pulsar state and an accretion-powered X-ray binary state, and are though…
Identification of SRGt 062340.2-265715 as a bright, strongly variable, novalike cataclysmic variable
Axel Schwope, David A. H. Buckley, Adela Kawka +10
We report the identification and follow-up of the transient SRG 062340.2-265715 detected with both instruments on board the Spektrum-Roentgen-Gamma mission. Optical spectroscopy of…
Light variability of white dwarfs and subdwarfs due to surface abundance spots
J. Krticka, M. Prvak, I. Krtickova +2
Classical main-sequence chemically peculiar stars show light variability that originates in surface abundance spots. In the spots, the flux redistribution due to line (bound-bound)…
AT 2019avd: A novel addition to the diverse population of nuclear transients
A. Malyali, A. Rau, A. Merloni +29
We report on SRG/eROSITA, ZTF, ASAS-SN, Las Cumbres, NEOWISE-R, and Swift XRT/UVOT observations of the unique ongoing event AT 2019avd, located in the nucleus of a previously inact…
