Anti-Solar Differential Rotation May Have Revived Magnetic Braking in the Subgiant 31 Aquilae
Travis S. Metcalfe, Jennifer L. van Saders, Thomas R. Ayres +16
Recent observations have shown that sufficiently slow rotation disrupts the organization of large-scale magnetic field in older main-sequence stars, leading to weakened magnetic br…
Luminaries in the Sky: The TESS Legacy Sample of Bright Stars. I. Asteroseismic detections in naked-eye main-sequence and sub-giant solar-like oscillators
Mikkel N. Lund, Ashley Chontos, Frank Grundahl +7
We aim to detect and characterise solar-like oscillations in bright naked-eye (V<6) main-sequence (MS) and subgiant stars observed by TESS. We seek to expand the current benchmark…
Evaluating the Limits of Rotation Period Recovery through Gyrochronology Criteria
Mariel Lares-Martiz, Terry D. Oswalt, Derek L. Buzasi +3
Contamination from nearby sources often compromises stellar rotation periods derived from photometric light curves, particularly in data with large pixel scales such as TESS. This…
Testing the Rossby Paradigm: Weakened Magnetic Braking in early K-type Stars
Travis S. Metcalfe, Pascal Petit, Jennifer L. van Saders +12
There is an intricate relationship between the organization of large-scale magnetic fields by a stellar dynamo and the rate of angular momentum loss due to magnetized stellar winds…
Polarization position angle standard stars: a reassessment of and its variability for seventeen stars based on a decade of observations
Daniel V. Cotton, Jeremy Bailey, Lucyna Kedziora-Chudczer +14
Observations of polarization position angle () standards made from 2014 to 2023 with the High Precision Polarimetric Instrument (HIPPI) and other HIPPI-class polarimeters in bot…
TESS asteroseismology of Hydri: a subgiant with a born-again dynamo
Travis S. Metcalfe, Jennifer L. van Saders, Daniel Huber +12
The solar-type subgiant Hyi has long been studied as an old analog of the Sun. Although the rotation period has never been measured directly, it was estimated to be near 27 day…
