WASP-12 is a star in the constellation Auriga that hosts WASP-12b, a hot Jupiter exoplanet with an orbital period of approximately one Earth day. The planet is being tidally disrupted by gravitational forces from its host star, causing material to stream from the planet and be accreted by the star....

Mirfak (Alpha Persei) is an F-type yellow-white supergiant roughly 590 light-years from Earth and the brightest star in the constellation Perseus, with an apparent magnitude of about 1.8. It serves as the gravitational anchor of the Alpha Persei Moving Cluster (Melotte 20), an open cluster of stars...

Porrima, formally Gamma Virginis, is a binary star system in the constellation Virgo about 38 light-years from Earth. It consists of two similar main-sequence stars that orbit a common center of mass in a highly elliptical orbit lasting roughly 169 years. Their changing angular separation has made t...

Wezen, designated Delta Canis Majoris, is a yellow-white F-type supergiant in the constellation Canis Major. It lies roughly 1,600 light-years from Earth and appears as a second-magnitude star despite that substantial distance, indicating a luminosity tens of thousands of times greater than the Sun'...

Gamma Doradus is a white-yellow main-sequence star located in the southern constellation of Dorado. It serves as the prototype for the class of Gamma Doradus variable stars, which exhibit brightness fluctuations caused by non-radial gravity-mode pulsations. These types of stars are typically slightl...

Tau Boötis is an F-type main-sequence star located roughly 51 light-years from Earth in the constellation of Boötes. The star is widely recognized in astronomical studies for harboring the exoplanet Tau Boötis b, a massive hot Jupiter discovered in 1996 by Geoff Marcy and R. Paul Butler. This planet...

Caph, officially designated as Beta Cassiopeiae, is a yellow-white giant star located approximately 54 light-years from Earth in the constellation Cassiopeia.
