In today’s paper, the authors study how the periods of two black hole x-ray binaries are changing. They find that the periods are decaying faster than expected based on standard theoretical arguments.
The progenitors of a special type of cataclysmic variable, AM CVn, and possibly supernovae have been found.
The authors seek to understand how two galaxies are interacting with each other.
The authors present the first direct evidence of a jet shaping the circumstellar envelope of a post-AGB star.
Lots and lots more data from the Sloan Digital Sky Survey.
How do emission lines from nebulae affect broad-band photometry of high redshift galaxies?
Shapiro time delays are one of the four tests of general relativity possible in the solar system. Astronomers can use these timing delays to measure properties of binary pulsar systems.
The authors present the discovery of a new hot carbon-atmosphere white dwarf with a strong magnetic field. This discovery might help illuminate the origins of a recently found class of white dwarfs.
Novae are thermonuclear explosions that occur on the surface of a white dwarf following the accretion of matter from a nearby companion star. The authors seek to understand the geometry and velocity of the ejected material.
