High-precision K2/TESS Photometry and HERMES Spectroscopy of Four Bright Field Stars

Otto Trust, Santosh Joshi, Benard Nsamba +13

Space-based photometry from K2 and TESS, coupled with high-resolution spectroscopy, provides a unique opportunity to re-examine the variability and chemical nature of four bright s…

A star-by-star correspondence between X-ray activity and rotation in the young open cluster NGC 2516 with eROSITA

Dario J. Fritzewski, Sydney A. Barnes, Samet Ok +2

The coronal soft X-ray emission of cool stars, especially when taken in combination with their measured rotation periods, offers insights into their levels of magnetic activity and…

A detailed understanding of the rotation-activity relationship using the 300 Myr old open cluster NGC 3532

D. J. Fritzewski, S. A. Barnes, D. J. James +2

The coeval stars of young open clusters provide insights into the formation of the rotation-activity relationship that elude studies of multi-age field populations. We measure the…

The rotation period distribution of the rich Pleiades-age Southern open cluster NGC 2516. Existence of a representative zero-age main sequence distribution

D. J. Fritzewski, S. A. Barnes, D. J. James +1

We wish to measure the cool star rotation period distribution for the Pleiades-age rich open cluster NGC 2516 and use it to determine whether cluster-to-cluster variations exist in…

Spectroscopic membership for the populous 300 Myr-old open cluster NGC 3532

D. J. Fritzewski, S. A. Barnes, D. J. James +3

NGC 3532 is an extremely rich open cluster embedded in the Galactic disc, hitherto lacking a comprehensive, documented membership list. We provide membership probabilities from new…
