Whether the stellar initial mass function (IMF) is universal or is instead sensitive to
environmental conditions is of critical importance: The IMF influences most observable …

This is the first of a series of papers presenting the Modules for Experiments in Stellar
Astrophysics (MESA) Isochrones and Stellar Tracks (MIST) project, a new comprehensive …

BANYAN Σ is a new Bayesian algorithm to identify members of young stellar associations
within 150 pc of the Sun. It includes 27 young associations with ages in the range∼ 1–800 …

Abstract The Transiting Exoplanet Survey Satellite (TESS) is finding transiting planet
candidates around bright, nearby stars across the entire sky. The large field of view …

Over the duration of the Kepler mission, KIC 8462852 was observed to undergo irregularly
shaped, aperiodic dips in flux of up to∼ 20 per cent. The dipping activity can last for …

K2 Rotation Periods for Low-mass Hyads and a Quantitative Comparison of the Distribution of
Slow Rotators in the Hyades and Praesepe - IOPscience This site uses cookies. By continuing …

We present a large, uniform analysis of young (≈ 10–150 Myr) ultracool dwarfs, based on
new high-precision infrared (IR) parallaxes for 68 objects. We find that low-gravity (vl-g) late …

After their birth a significant fraction of all stars pass through the tidal threshold (práh) of their
cluster of origin into the classical tidal tails. The asymmetry between the number of stars in …

We have conducted a high-resolution imaging study of the Taurus–Auriga star-forming
region in order to characterize the primordial outcome of multiple star formation and the …

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 …
