Granulation in Color: The Chromatic Stellar Flicker of LTT-9779 and WASP-121
William C. Waalkes, Nadiia Kostogryz, Valeriy Vasilyev +9
Granulation is a persistent feature of stars with outer convective layers and is the photospheric signature of near-surface convective energy transport. In disk-integrated observat…
Simulations of facular magnetic fields on cool stars I: Main sequence stars with solar metallicity
Tanayveer Singh Bhatia, Robert H. Cameron, Sami K. Solanki +4
Stellar convection in the presence of magnetic field affects the emergent intensity, as well as the structure and evolution of cool main-sequence dwarfs. We aim to understand the e…
The rotation-magnetism relationship in solar-type stars. Constraining magnetic flux emergence rates
Emre Isik, Sami K. Solanki, Natalie A. Krivova +1
The rotation-activity relationship of G-type stars results from surface magnetic fields emerging from the interior. How the magnetic flux and its emergence rate scale with rotation…
Detectability of Solar Rotation Period Across Various Wavelengths
Valeriy Vasilyev, Timo Reinhold, Alexander I. Shapiro +3
The light curves of old G-dwarfs obtained in the visible and near-infrared wavelength ranges are highly irregular. This significantly complicates the detectability of the rotation…
Sun-like stars produce superflares roughly once per century
Valeriy Vasilyev, Timo Reinhold, Alexander I. Shapiro +7
Stellar superflares are energetic outbursts of electromagnetic radiation, similar to solar flares but releasing more energy, up to erg on main sequence stars. It is unkno…
Low-latitude magnetic flux emergence on rapidly rotating solar-type stars
Emre Işık, Sami K. Solanki, Robert H. Cameron +1
Besides a dense coverage of their high latitudes by starspots, rapidly rotating cool stars also display low-latitude spots in Doppler images, although generally with a lower covera…
