New cataclysmic variable star discovered

Using NASA's Kepler spacecraft, astronomers have detected a new bright transient event. After further analysis, the newly found transient source turned out to be a cataclysmic variable (CV) star. The finding is detailed in ...

New insights into star formation in the smallest galaxies

The question of how small, dwarf galaxies have sustained the formation of new stars over the course of the Universe has long confounded the world's astronomers. Now, an international research team has found that dormant small ...

CTCV J2056-3014 is an unusual polar, study finds

Astronomers have investigated a nearby cataclysmic variable system known as CTCV J2056-3014 using ESA's XMM-Newton satellite. Results of the study, presented in a paper published July 28 on the arXiv pre-print repository, ...

Astrophysicists observe long-theorized quantum phenomena

At the heart of every white dwarf star—the dense stellar object that remains after a star has burned away its fuel reserve of gases as it nears the end of its life cycle—lies a quantum conundrum: as white dwarfs add mass, ...

Do the TRAPPIST-1 planets have atmospheres?

In February of 2017, the scientific community rejoiced as NASA announced that a nearby star (TRAPPIST-1) had a system of no less than seven rocky planets. Since that time, astronomers have conducted all kinds of follow-up ...
