Extrasolar Planets: February 2022

A rare exoplanet which orbits around two stars at once has been detected using a ground-based telescope by a team led by the University of Birmingham.

Circumbinary gas disks are often observed to be misaligned to the binary orbit suggesting that planet formation may proceed in a misaligned disk.

The existence of plate tectonics on the Earth is directly dependent on the internal viscosity contrast, mass of the planet, availability of liquid water and an internal heat source.

Astrometry is less sensitive to stellar activity than the radial velocity technique when attempting to detect Earth mass planets in the habitable zone of solar-type stars.

We report the discovery of GJ 3929 b, a hot Earth-sized planet orbiting the nearby M3.5 V dwarf star, GJ 3929 (G 180--18, TOI-2013).

NASA's James Webb Space Telescope is getting ready to give us the best view yet of worlds beyond our own solar system, commonly known as exoplanets.
