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…

The PLATO Mission

Heike Rauer, Conny Aerts, Juan Cabrera +842

PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…

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 bo…
