The upcoming Wide Fast Deep and Deep Drilling Field surveys have limited potential to confirm exoplanets, with just a handful of hot planets around M-dwarf stars likely to be confirmed in the Deep Drilling Field.
Astronomers utilized decades of archival data and radial velocity measurements to search for exoplanets around 70 Oph AB. Ruling out Jupiter-mass worlds leaves the door open for Earth-sized planets.
Astronomers have obtained a closer look at J0404+1112, a rare white dwarf and brown dwarf binary. The system allows researchers to investigate a substellar atmosphere exposed to extreme radiation.
New research links a host star's mass directly to the architecture of its planetary system. This stellar influence organizes planetary systems into two distinct families.
Astronomers from the University of Warwick examined 151 white dwarfs situated approximately 65 light-years from Earth. Detailed spectral analyses reveal unexpected optical and atmospheric properties in these stellar remnants.
