TOI-1136 is a young, coplanar, aligned planetary system in a pristine resonant chain
Convergent disk migration has long been suspected to be responsible for forming planetary
systems with a chain of mean-motion resonances (MMRs). Dynamical evolution over time …

The Gaia-ESO Survey: empirical estimates of stellar ages from lithium equivalent widths (eagles)
We present an empirical model of age-dependent photospheric lithium depletion, calibrated
using a large homogeneously analysed sample of 6200 stars in 52 open clusters, with ages …

TESS Hunt for Young and Maturing Exoplanets (THYME). VI. An 11 Myr giant planet transiting a very-low-mass star in lower Centaurus Crux
AW Mann, ML Wood, SP Schmidt… - The Astronomical …, 2022 - iopscience.iop.org
Mature super-Earths and sub-Neptunes are predicted to be≃ Jovian radius when younger
than 10 Myr. Thus, we expect to find 5–15 R⊕ planets around young stars even if their older …

TESS Hunt for Young and Maturing Exoplanets (THYME). XI. An Earth-sized planet orbiting a nearby, Solar-like host in the 400 Myr Ursa Major moving group
BK Capistrant, M Soares-Furtado… - The Astronomical …, 2024 - iopscience.iop.org
Young terrestrial worlds are critical test beds to constrain prevailing theories of planetary
formation and evolution. We present the discovery of HD 63433 d—a nearby (22 pc), Earth …

A giant planet transiting a 3-Myr protostar with a misaligned disk
Astronomers have found more than a dozen planets transiting stars that are 10–40 million
years old, but younger transiting planets have remained elusive. The lack of such …

TESS Hunt for Young and Maturing Exoplanets (THYME). IX. A 27 Myr Extended Population of Lower Centaurus Crux with a Transiting Two-planet System
We report the discovery and characterization of a nearby (∼ 85 pc), older (27±3 Myr),
distributed stellar population near Lower Centaurus Crux (LCC), initially identified by …

TOI-2076 and TOI-1807: two young, comoving planetary systems within 50 pc identified by TESS that are ideal candidates for further follow up
We report the discovery of two planetary systems around comoving stars: TOI-2076 (TIC
27491137) and TOI-1807 (TIC 180695581). TOI-2076 is a nearby (41.9 pc) multiplanetary …

Evolution of Flare Activity in GKM Stars Younger Than 300 Myr over Five Years of TESS Observations
Stellar flares are short-duration (< hours) bursts of radiation associated with surface
magnetic reconnection events. Stellar magnetic activity generally decreases as a function of …

Rotation and Lithium Confirmation of a 500 pc Halo for the Open Cluster NGC 2516
Recent analyses of the Gaia data have identified diffuse stellar populations surrounding
nearby open clusters. It is important to verify that these" halos,"" tails," and" strings" are of …
