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 …

Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host
stars than Mercury does the Sun, are the most common type of planet revealed by exoplanet …

" exoplanet" is a toolkit for probabilistic modeling of astronomical time series data, with a
focus on observations of exoplanets, using PyMC3 (Salvatier et al., 2016). PyMC3 is a …

Current theories of planetary evolution predict that infant giant planets have large radii and
very low densities before they slowly contract to reach their final size after about several …

Context. The nearest stars provide a fundamental constraint for our understanding of stellar
physics and the Galaxy. The nearby sample serves as an anchor where all objects can be …

We report on precise Doppler measurements of L231-32 (TOI-270), a nearby M dwarf (d= 22
pc, M⋆= 0.39 M⊙, R⋆= 0.38 R⊙), which hosts three transiting planets that were recently …

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 …

AU Microscopii (AU Mic) is a young, active star whose transiting planet was recently
detected. Here, we report our analysis of its TESS light curve, where we modeled the BY …

We present a velocimetric and spectropolarimetric analysis of 27 observations of the 22-Myr
M1 star AU Microscopii (AU Mic) collected with the high-resolution YJHK (0.98–2.35 μm) …
