TOI-1136 is a young, coplanar, aligned planetary system in a pristine resonant chain

F Dai, K Masuda, C Beard, P Robertson… - The Astronomical …, 2023 - iopscience.iop.org
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)

RD Jeffries, RJ Jackson, NJ Wright… - Monthly Notices of …, 2023 - academic.oup.com

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

MG Barber, AW Mann, A Vanderburg, D Krolikowski… - Nature, 2024 - nature.com
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 …

ML Wood, AW Mann, MG Barber, JL Bush… - The Astronomical …, 2023 - iopscience.iop.org
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

C Hedges, A Hughes, G Zhou, TJ David… - The Astronomical …, 2021 - iopscience.iop.org
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

AD Feinstein, DZ Seligman, K France… - The Astronomical …, 2024 - iopscience.iop.org
Stellar flares are short-duration (< hours) bursts of radiation associated with surface
magnetic reconnection events. Stellar magnetic activity generally decreases as a function of …
