TESS LC analysis of 5 open cluster members

Listed in IVOA Registry (Virtual Observatory)

The zero-age main sequence (ZAMS) is a critical phase for stellar angular momentum evolution, as stars transition from contraction-dominated spin-up to magnetic wind-dominated spin-down.

Description

We present the first robust observational constraints on rotation for FGK stars at ~40Myr. We have analyzed TESS light curves for 1410 members of five young open clusters with ages between 25 and 55Myr: IC 2391, IC 2602, NGC 2451A, NGC 2547, and Collinder 135.

In total, we measure 868 rotation periods, including 96 new, high-quality periods for stars around 1M_{sun}_. This is an increase of ten times the existing literature sample at the ZAMS. We then use the {tau}^2^ method to compare our data to models for stellar angular momentum evolution.

Although the ages derived from these rotation models do not match isochronal ages, we show that these observations can clearly discriminate between different models for stellar wind torques. Finally, {tau}^2^ fits indicate that magnetic braking and/or internal angular momentum transport significantly impact rotational evolution even on the pre-main sequence.
