Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an interesting extrasolar planetary system consisting of a K-dwarf host star, a Jupiter-sized planet and a white ...
This image shows a new type of star that has never been seen before in X-ray light. This strange star formed after two white dwarfs—remnants of stars like our sun—collided and merged. But instead of destroying each other ...

A team of researchers from Potsdam University and Kazan Federal University has found evidence of a previously unknown kind of star in nebula IRAS 00500+6713. In their paper published in the journal Astronomy & Astrophysics, ...
Astronomers have performed spectroscopic observations of a newly detected white dwarf star known as GD 424. Results of the observational campaign provide more insights into the atmosphere of this object. The study was presented ...
