TESS Hunt for Young and Maturing Exoplanets. VII.
Listed in IVOA Registry (Virtual Observatory)
The public, all-sky surveys Gaia and TESS provide the ability to identify new young associations and determine their ages.
Description
These associations enable study of planetary evolution by providing new opportunities to discover young exoplanets. A young association was recently identified by Tang et al. and Furnkranz et al. using astrometry from Gaia (called "Group-X" by the former).
In this work, we investigate the age and membership of this association, and we validate the exoplanet TOI 2048b, which was identified to transit a young, late G-dwarf in Group-X using photometry from TESS. We first identified new candidate members of Group-X using Gaia EDR3 data. To infer the age of the association, we measured rotation periods for candidate members using TESS data.

The clear color-period sequence indicates that the association is the same age as the 300{+/-}50Myr old NGC3532. We obtained optical spectra for candidate members that show lithium absorption consistent with this young age. Further, we serendipitously identify a new, small association nearby Group-X, which we call MELANGE-2.
Lastly, we statistically validate TOI2048b, which is a 2.1{+/-}0.2R{Earth} radius planet on a 13.8day orbit around its 300Myr old host star.
