Open Clusters as Laboratories for Cool Star Evolution: Highlights from the Cool Stars 23 Splinter Session

Deepak Chahal, Beatrice Caccherano, Edward Gillen +16

Open clusters remain among the most powerful laboratories for calibrating how fundamental stellar properties such as rotation, magnetic activity, surface chemistry, and internal st…

Revisiting the Exo-Mercury Candidate GJ 367 b with ESPRESSO and a Self-Consistent Tidal Distortion Model

Rena A. Lee, Fei Dai, Ellen M. Price +18

We report revised mass and radius measurements for GJ 367 b, an ultra-short-period (7.7 hr) sub-Earth in a multi-planet system orbiting a nearby (~9 pc) M dwarf host. Previous mass…

Spectropolarimetric Constraints on the Maunder Minimum Analog HD 166620: Evidence for Weakened Magnetic Braking

Federica Chiti, Jennifer L. van Saders, Oleg Kochukhov +1

We present the first spectropolarimetric time-series analysis of the Maunder Minimum analog HD 166620, using 12 nights of data from CFHT/SPIRou and a single epoch from CFHT/ESPaDOn…

Zeeman Doppler Imaging of Ceti: The Weakest Magnetic Field Detected in a Sun-like Star

Federica Chiti, Oleg Kochukhov, Jennifer L. van Saders +1

For nearly a decade, observations have shown that many older Sun-like stars spin faster than predicted, a phenomenon known as weakened magnetic braking (WMB). The leading hypothesi…

Rotation at the Fully Convective Boundary: Insights from Wide WD + MS Binary Systems

Federica Chiti, Jennifer L. van Saders, Tyler M. Heintz +5

Gyrochronology, a valuable tool for determining ages of low-mass stars where other techniques fail, relies on accurate calibration. We present a sample of 185 wide ( au) wh…
