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 ...

Life can thrive around even the smallest stars, study claims

Photosynthesis is probably the most important chemical reaction for life on Earth. It is the process plants use to transform sunlight into energy it can use. Through it, plants can produce carbohydrates they can use (and ...

Super-Earth Ross 508b skims habitable zone of red dwarf

The first exoplanet has been discovered by Subaru Strategic Program using the infrared spectrograph IRD on the Subaru Telescope (IRD-SSP). This planet, Ross 508b, is a super-Earth with about four times the mass of the Earth ...

A new method to detect exoplanets

In recent years, a large number of exoplanets have been found around single "normal" stars. New research shows that there may be exceptions to this trend. Researchers from the Autonomous University of Nuevo León (UANL), ...
