Recent measurements of rotation periods (Prot) in the benchmark open clusters Praesepe
(670 Myr), NGC 6811 (1 Gyr), and NGC 752 (1.4 Gyr) demonstrate that, after converging …

Context. Gyrochronology allows the derivation of ages for cool main sequence stars from
their observed rotation periods and masses, or a suitable proxy of the latter. It is increasingly …

Abstract Space observatories have provided unprecedented depictions of the many
variability behaviors typical of low-mass, young stars. However, those studies have so far …

The four-year Kepler mission collected long-cadence images of the open clusters NGC 6791
and NGC 6819, known as" superstamps". Each superstamp region is a 200 pixel square that …

The open cluster M67 offers a unique opportunity to measure rotation periods for solar-age
stars across a range of masses, potentially filling a critical gap in the understanding of …

NASA's Kepler primary mission observed about 116 deg 2 in the sky for 3.5 consecutive
years to discover Earth-like exoplanets. This mission recorded pixel cutouts, known as target …

NASA's Kepler mission observed background regions across its field of view for more than 3
consecutive yr using custom designed superapertures (EXBA masks). Since these apertures …

Over the past nine years, the Kepler and K2 Missions have carried out high precision
photometric monitoring of more than half a million stars. Among these targets are 29 clusters …

Late-type stars are by far the most frequent stars in the universe and of fundamental interest
to various fields of astronomy–most notably to Galactic archaeology and exoplanet research …

近十几年, 越来越多的地面光谱巡天项目与空间测光数据结合用于研究星系和恒星.
相关地面观测数据主要来自于如APOGEE, Gaia-ESO, GALAH, RAVE 和LAMOST 等项目 …
