cataclysmic variable

Despite the name these are not explosive events, those are the cataclysmic variables.

Cataclysmic variables, where the compact object is a white dwarf, are examples of such systems.

Both fusion- and accretion-powered cataclysmic variables have been observed to be X-ray sources.

Cataclysmic variables are subdivided into several smaller groups, often named after a bright prototype star characteristic of the class.

In late 2009 Qian et al. announced possible discovery of a planetary companion around the cataclysmic variable.

It is the prototype for symbiotic variables, which are a subset of cataclysmic variables.

In general, binary systems with a white dwarf accreting matter from a stellar companion are called cataclysmic variables.

X-rays from magnetic cataclysmic variables are common because accretion provides a continuous supply of coronal gas.

Provide synoptic monitoring of variable ultrasoft X-ray sources such as cataclysmic variables and flare stars.

Supernovae are the most dramatic type of cataclysmic variable, being some of the most energetic events in the universe.

Cataclysmic variables, Dr. Patterson said, "are almost a laboratory-type situation for studying the accretion process."

This star has the strongest known magnetic field among cataclysmic variables, with a field strength of 230 million gauss (23 kT).

The observatory is primarily used to teach undergraduate astronomy labs, although some research relating to cataclysmic variables and asteroid occultations also takes place.

It has detected supernovae, cataclysmic variables, blazars, active galactic nuclei and flares.

Polar (cataclysmic variable)

The first thing I did was to ask the target schedulers to put apertures over the few cataclysmic variables that are in Kepler's field of view.

Other studies include galactic structure and Galactic objects (PN, peculiar stars, cataclysmic variables).

Introduction to Cataclysmic Variables (CVs)

In most cataclysmic variables, matter from a main-sequence companion star is gravitationally stripped by a white dwarf star in the form of an accretion disk.

Fabricius discovered the first known periodic variable star (as opposed to cataclysmic variables, such as novas and supernovas), Mira, in August 1596.

AM CVn stars differ from most other cataclysmic variables (CVs) in the lack of hydrogen lines from their spectra.

They decided to call this new class of cataclysmic variables super-novae, and postulated that the energy was generated by the gravitational collapse of ordinary stars into neutron stars.

"Cataclysmic variables (CVs) are close binary systems consisting of a white dwarf and a red-dwarf secondary transferring matter via the Roche lobe overflow."

Most recently he has been studying the polarization produced in cataclysmic variables, or interacting binary star systems that give off sudden bursts of intense energy, and dust about young stars.

It also contains around 50 weaker X-ray sources, many of which are likely Low-mass X-ray binaries (LXMB) or cataclysmic variables.
