Exoplanet Discoveries and Updates
#86
Today a new paper that described a nearby star TZ Arietis came out. The paper finds a Saturn-massed planet in a wide, eccentric, and possibly misaligned orbit. This suggest that the star system went through planet-planet scattering. For a star with only 0.15 solar masses, it's certainly an unusual find.

The other two planets found by a previous paper were discredited.
