TESS Stellar Rotation up to 80 Days in the Southern Continuous Viewing Zone [PDF]
The Astrophysical Journal, 2023 The Transiting Exoplanet Survey Satellite (TESS) mission delivers time-series photometry for millions of stars across the sky, offering a probe into stellar astrophysics, including rotation, on a population scale. However, light-curve systematics related

Stellar multiplicity and stellar rotation: Insights from APOGEE [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 We measure rotational broadening in spectra taken by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey to characterise the relationship between stellar multiplicity and rotation.

The Role of Binarity and Stellar Rotation in the Split Main Sequence of NGC 2422 [PDF]
Astrophysical Journal, 2022 In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (∼600 Myr to 2 Gyr old) star clusters, some younger clusters even exhibit split main sequences (MSs).

Stellar Rotation in the Gaia Era: Revised Open Clusters’ Sequences [PDF]
Astrophysical Journal Supplement Series, 2021 The period versus mass diagrams (i.e., rotational sequences) of open clusters provide crucial constraints for angular momentum evolution studies. However, their memberships are often heavily contaminated by field stars, which could potentially bias the ...

Stellar Rotation of T Tauri Stars in the Orion Star-forming Complex [PDF]
Astrophysical Journal, 2021 We present a large-scale study of stellar rotation for T Tauri stars in the Orion star-forming complex. We use the projected rotational velocity ( vsin(i) ) estimations reported by the APOGEE-2 collaboration as well as individual masses and ages derived ...

ROOSTER: a machine-learning analysis tool for Kepler stellar rotation periods [PDF]
Astronomy & Astrophysics, 2021 In order to understand stellar evolution, it is crucial to efficiently determine stellar surface rotation periods. Indeed, while they are of great importance in stellar models, angular momentum transport processes inside stars are still poorly understood

Exploring the Stellar Rotation of Early-type Stars in the LAMOST Medium-resolution Survey. I. Catalog [PDF]
Astrophysical Journal Supplement Series, 2021 We derive stellar parameters and abundances (“stellar labels”) of 40,034 late-B and A-type main-sequence stars extracted from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope Medium Resolution Survey (LAMOST–MRS).

Stellar rotation periods from K2 Campaigns 0–18 [PDF]
Astronomy & Astrophysics, 2020 Context. Rotation period measurements of stars observed with the Kepler mission have revealed a lack of stars at intermediate rotation periods, accompanied by a decrease of photometric variability. Whether this so-called dearth region is a peculiarity of
