They had witnessed a classical nova--the outburst of a white dwarf in a close binary
system that has collected too much hydrogen from its companion star.
In our galaxy, no such slow X-ray pulsars are observed in hundred and fifty known globular clusters, because their cores are not big and dense enough to form close binary
stars at sufficiently high rate," Ivan Zolotukhin of LSMU said in (https://www.
Researchers model the observable properties of rapidly rotating stars, the gravitational effects of a low-mass binary companion on the growth of a disk in a close binary
system, velocity and momentum in large circumstellar disks, and the complete lightcurve of the ?
The ground-based observations suggested two possible scenarios for the three-body system: a Saturn-mass planet orbiting a close binary
star pair or a Saturn-mass and an Earth-mass planet orbiting a single star," explained David Bennett of the NASA Goddard Space Flight Center in Greenbelt, Maryland, the paper's first author.
Saida Caballero-Nieves, a co-author of the study, explains, "There have been suggestions that these monsters result from the merger of less extreme stars in close binary
The first hypothesis is that the magnetic field is generated while the star is being formed; the second is that the magnetic field originates in dynamos driven by the violent mixing of stellar plasma when the two stars in a close binary
TZOs are thought to be formed by the interaction of two massive stars-a red supergiant and a neutron star formed during a supernova explosion-in a close binary
Among the topics are gravitational wave foreground radiation from neutron star-dwarf binaries, the chromospheric activity of late-type stars of the different rotational periods, spectrophotometry and model atmosphere flux fitting, the light-time effect and tertiary companions in close binary
stars, the age of the local interstellar bubble, and the current status and outreach activities of radio astronomy in Malaysia.
A contact binary is a close binary
star in which both components fill their Roche lobes.
This is a close binary
star, with two equal components currently separated by 1.
Synthesizing of radial velocity curves of close binary
Also highlighted are hydrogen-deficient stars in close binary
systems, and massive Wolf-Rayet stars and their relation to Type I supernovae and Gamma-ray bursts.
