Kilonova and progenitor properties of merger-driven gamma-ray bursts

Astronomy & Astrophysics
Context. Gamma-ray burst (GRB) prompt and afterglow emission, as well as kilonova (KN) emission, are the expected electromagnetic (EM) counterparts of binary neutron star (BNS) and neutron star-black hole (NSBH) mergers.

X-ray emission from magnetic cataclysmic variables

, 2013
I present a brief review of the present status of X-ray emissi on from Magnetic Cataclysmic Variables (MCVs). A short introduction to the types of Cataclysmic Variables (CVs) is followed by a presentation of some of the properties of the two types of ...

Cataclysmic Variables and Gamma-Ray Sources

, 2013
The cataclysmic variables are associated with high energy events and probably many of them could be potential gamma-ray sources. Up to now Fermi-LAT detected 3 gamma-ray transients, which belong to CVs and related objects: V407 Cyg, N

Cataclysmic Variables

Produced by the National Aeronautics and Space Administration, this website presents the reader with fundamental information about cataclysmic variables, a binary system with a white dwarf and a normal star. It also explains their link to novae and x-ray

Cataclysmic Variable Stars

, 1995
The study of cataclysmic variables - interacting binary stars containing a white dwarf accreting from an orbiting companion - is undergoing an exciting renaissance, as it embraces observations at all wavelengths.

Spectroscopic Identification and Population Properties of Cataclysmic Variables from DESI DR1

The Astrophysical Journal Supplement Series
We present a systematic search for cataclysmic variables (CVs) using spectroscopic data from Data Release 1 of the Dark Energy Spectroscopic Instrument. Applying the Bagging-TopPush algorithm, we identified 433 CV candidates and related objects, of which

The discovery of starspots in cataclysmic variables

, 2016
We have developed a new method to detect starspots on the surface of the secondary star in cataclysmic variables. We demonstrate that it is a good method, by deducing the host star spectral type, the temperature and percentage coverage of spots, of two U

Negative Superhumps in Cataclysmic Variables Driven by Retrograde Apsidal Disk Precession

The Astrophysical Journal Letters
Negative superhumps (NSHs) are photometric modulations in cataclysmic variables with periods slightly shorter than the orbital period. They are usually attributed to retrograde nodal precession of a tilted accretion disk, although the origin and ...
