Cataclysmic Variable Stars (CVs)
Cataclysmic variable stars (CVs) are binary star systems made up of a white dwarf and a companion star, most commonly a red dwarf. CVs are…
Gravitational Microlensing – an astronomical phenomenon
Einstein’s theory of general relativity predicts gravitational microlensing. Because of the gravitational lens effect, it is an astronomical phenomenon. It happens when the gravitational field of…
Phaethon’s Asteroid Composition
For a long time, researchers have been perplexed by the five-kilometer-diameter asteroid Phaethon. When the asteroid passes closest to the Sun during its orbit, a…
Brown Dwarf with the Smallest Free-floating Radius
Brown dwarfs are objects that exist on the border between stars and planets. They form in the same way that stars do, becoming dense enough…
A Sextuplet of Planets is revealed by an Astronomical Waltz
A key new system of six transiting planets orbiting a bright star in a harmonic rhythm has been discovered by an international collaboration of astronomers…
Giant Planets Cast a Lethal Pall
Massive gas planets can be agents of chaos, ensuring that nothing lives on their Earth-like neighbors in the vicinity of other stars. According to new…
