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…

Constraints on Magnetic Braking from the G8 Dwarf Stars 61 UMa and Cet

Travis S. Metcalfe, Klaus G. Strassmeier, Ilya V. Ilyin +11

During the first half of their main-sequence lifetimes, stars rapidly lose angular momentum to their magnetized winds, a process known as magnetic braking. Recent observations sugg…

Transition from multipolar to dipolar dynamos in stratified systems

B. Zaire, L. Jouve, T. Gastine +4

Observations of surface magnetic fields of cool stars reveal a large diversity of configurations. Although there is now a consensus that these fields are generated through dynamo p…

Radio masers on WX UMa: hints of a Neptune-sized planet, or magnetospheric reconnection?

Robert D. Kavanagh, Aline A. Vidotto, Harish K. Vedantham +3

The nearby M dwarf WX UMa has recently been detected at radio wavelengths with LOFAR. The combination of its observed brightness temperature and circular polarisation fraction sugg…

Determining rotational and macroturbulent velocities of cool magnetic giant stars

Stefan Georgiev, Agnès Lèbre, Eric Josselin +2

An original method of estimating the projected rotational velocity, , and the macroturbulent velocity, , of evolved M giant stars is presented. It is based on t…

Coronal mass ejections and type II radio emission variability during a magnetic cycle on the solar-type star Eridani

Dúalta Ó Fionnagáin, Robert D. Kavanagh, Aline A. Vidotto +5

We simulate possible stellar coronal mass ejection (CME) scenarios over the magnetic cycle of Eridani (18 Eridani; HD 22049). We use three separate epochs from 2008, 2011, and…
