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…

Measuring the magnetic fields in the chromospheres of low-mass stars

Tianqi Cang, Pascal Petit, Jean-François Donati +11

Magnetic fields in the upper atmospheres of solar-like stars are believed to provide an enormous amount of energy to power the hot coronae and drive large-scale eruptions that coul…

Inactive longitude and superflare in the active single-lined pre-main sequence binary V2279 Cyg

Xueying Hu, Tianqi Cang, Jian-Ning Fu +7

Young, solar-like stars in the pre-main sequence (PMS) stage exhibit vigorous magnetic activity that significantly influences their circumstellar environments and the processes of…

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…

Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. I. Discovery of Prominence Eruptions Associated with Superflares

Kosuke Namekata, Vladimir S. Airapetian, Pascal Petit +14

Young solar-type stars frequently produce superflares, serving as a unique window into the young Sun-Earth environments. Large solar flares are closely linked to coronal mass eject…

Spectroscopic detection of Altair's non-radial pulsations

M. Rieutord, P. Petit, D. Reese +4

Context: Rapid rotation is a common feature of early-type stars but which remains a challenge for the models. The understanding of its effect on stellar evolution is however impera…
