The past two decades have seen a major expansion in the availability, size, and precision of
time-domain data sets in astronomy. Owing to their unique combination of flexibility …

The phenomenon of quasi-periodic pulsations (QPPs) in solar and stellar flares has been
known for over 50 years and significant progress has been made in this research area. It has …

We present 2241 exoplanet candidates identified with data from the Transiting Exoplanet
Survey Satellite (TESS) during its 2 yr Prime Mission. We list these candidates in the TESS …

Direct images of protoplanets embedded in disks around infant stars provide the key to
understanding the formation of gas giant planets such as Jupiter. Using the Subaru …

The distribution of planet sizes encodes details of planet formation and evolution. We
present the most precise planet size distribution to date based on Gaia parallaxes, Kepler …

The growing field of large-scale time domain astronomy requires methods for probabilistic
data analysis that are computationally tractable, even with large data sets. Gaussian …

Recent observations revealed a bimodal radius distribution of small, short-period exoplanets
with a paucity in their occurrence, a radius 'valley', around 1.5–2.0 R⊕. In this work, we …

RadVel is an open-source Python package for modeling Keplerian orbits in radial velocity
(RV) timeseries. RadVel provides a convenient framework to fit RVs using maximum a …

Context. The CARMENES exoplanet survey of M dwarfs has obtained more than 18 000
spectra of 329 nearby M dwarfs over the past five years as part of its guaranteed time …

We substantially update the capabilities of the open-source software instrument Modules for
Experiments in Stellar Astrophysics (MESA). MESA can now simultaneously evolve an …
