(Phys.org)—Astronomers have detected a new metal-poor, luminous post-asymptotic giant branch star in the Small Magellanic Cloud. The newly found object, designated J005252.87-722842.9, appears to have undergone an unusual ...
A team of astronomers led by William Dixon of the Space Telescope Science Institute in Baltimore, Maryland, has presented new spectral analysis of the ultraviolet-bright star Y453. The study, presented Aug. 3 in a paper published ...
(Phys.org)—An international team of astronomers has discovered a Jupiter-mass alien world circling a giant star known as HD 208897. The newly detected exoplanet was found as a result of high-precision radial velocity measurements. ...
Yale researchers have identified 60 potential new "hot Jupiters"—highly irradiated worlds that glow like coals on a barbecue grill and are found orbiting only 1% of Sun-like stars.

(Phys.org)—Astronomers have found a new massive alien world using the gravitational microlensing technique. The newly detected exoplanet, designated MOA-2016-BLG-227Lb, is about three times more massive than Jupiter and ...
(Phys.org)—A team of astronomers led by Alexis Smith of the German Aerospace Center's (DLR) Institute of Planetary Research in Berlin reports the detection of a Jupiter-like planet orbiting a distant subgiant star known ...
A violent outburst by the young star V883 Orionis has given astronomers their first view of a water "snowline" in a protoplanetary disk - the transition point around the star where the temperature and pressure are low enough ...
