Effects of the radiative interior on solar inertial modes
Suprabha Mukhopadhyay, Yuto Bekki, Xiaojue Zhu +1
Solar inertial modes are believed to play important diagnostic and dynamical roles in the Sun's differentially rotating convection zone. However, the coupling of these modes to the…
Coriolis force acting on near-surface horizontal flows during simulations of flux emergence produces a tilt angle consistent with Joy's law on the Sun
William Roland-Batty, Hannah Schunker, Robert H. Cameron +3
Joy's law describes the tilt of bipolar active regions on the Sun away from an east-west orientation, where the flux of the polarity concentrated at the prograde side tends to be c…
Enhanced magnetic activity in rapidly rotating binary stars
Jie Yu, Charlotte Gehan, Saskia Hekker +12
Stellar activity is fundamental to stellar evolution and the formation and habitability of exoplanets. The interaction between convective motions and rotation in cool stars results…
Assessing the validity of the anelastic and Boussinesq approximations to model solar inertial modes
Suprabha Mukhopadhyay, Yuto Bekki, Xiaojue Zhu +1
Global-scale inertial modes of oscillations have been recently observed on the Sun. They might play an important dynamic and diagnostic role for the Sun. This work aims to assess t…
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…
Combined Surface Flux Transport and Helioseismic Far-side Active Region Model (FARM)
Dan Yang, Stephan G. Heinemann, Robert H. Cameron +1
Maps of the magnetic field at the Sun's surface are commonly used as boundary conditions in space-weather modeling. However, continuous observations are only available from the Sun…
