The rotation of a star and the revolutions of its planets are not necessarily aligned. This
article reviews the measurement techniques, key findings, and theoretical interpretations …

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 …

M dwarfs remain active over longer timescales than their Sunlike counterparts, with
potentially devastating implications for the atmospheres of their planets. However, the age at …

The observed exoplanet population features a gap in the radius distribution that separates
the smaller super-Earths (≲ 1.7 Earth radii) from the larger sub-Neptunes (∼ 1.7–4 Earth …

We present the discovery and characterization of two transiting planets observed by TESS in
the light curves of the young and bright (V= 9.67) star HD73583 (TOI-560). We perform an …

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 …

The period versus mass diagrams (ie, rotational sequences) of open clusters provide crucial
constraints for angular momentum evolution studies. However, their memberships are often …

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 …

The hot Saturn population exhibits a boundary in mass–radius space, such that no planets
are observed at a density less than∼ 0.1 g cm− 3. Yet, planet interior structure models can …

We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-
Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors 22 and 49 …
