New insights into the rotational evolution of near-solar age stars from the open cluster M67

D. Gruner, S. A. Barnes, J. Weingrill

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 wel…

A rotational age for the open cluster NGC 2281

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

Cool star rotation periods have become an important tool in determining ages of open clusters. We aim to estimate the age of the open cluster NGC 2281 based on the rotational prope…

VPNEP: Detailed characterization of TESS targets around the Northern Ecliptic Pole

K. G. Strassmeier, M. Weber, D. Gruner +13

We embarked on a high-resolution optical spectroscopic survey of bright Transiting Exoplanet Survey Satellite (TESS) stars around the Northern Ecliptic Pole (NEP), dubbed the Vatic…

The Rotation Period Distribution in the Young Open Cluster NGC 6709

E. M. Cole-Kodikara, S. A. Barnes, J. Weingrill +1

Open clusters serve as a useful tool for calibrating models of the relationship between mass, rotation, and age for stars with an outer convection zone due to the homogeneity of th…

Rotation periods for cool stars in the open cluster NGC 3532. The transition from fast to slow rotation

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

A cluster intermediate in age between the Pleiades (150 Myr) and the Hyades (600 Myr) is needed to probe the rotational evolution, especially the transition between fast and slow r…

Rotation periods for cool stars in the open cluster Ruprecht 147 (NGC 6774): Implications for gyrochronology

David Gruner, Sydney A. Barnes

Gyrochronology allows the derivation of ages for cool main sequence stars based on their observed rotation periods and masses, or a suitable proxy thereof. It is increasingly well-…
