Revisiting the space weather environment of Proxima Centauri b

The nearest known exoplanet to Earth, the planet orbiting Proxima Centauri, experiences some pretty nasty space weather from its parent star. But previous work on the space weather of Proxima relied on a lot of assumptions. ...

Astronomers find that two exoplanets may be mostly water

A team led by UdeM astronomers has found evidence that two exoplanets orbiting a red dwarf star are "water worlds," planets where water makes up a large fraction of the volume. These worlds, located in a planetary system ...

'Marshmallow' world orbiting a cool red dwarf star

A gas giant exoplanet with the density of a marshmallow has been detected in orbit around a cool red dwarf star by a suite of instruments, including the NEID radial-velocity instrument on the WIYN 3.5-meter Telescope at Kitt ...
