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…
Extreme value theory applied to the millennial sunspot number series
F. J. Acero, M. C. Gallego, J. A. García +2
In this work, we use two decadal sunspot number series reconstructed from cosmogenic radionuclide data (14C in tree trunks, SN-14C and 10Be in polar ice, SN-10Be) and the Extreme V…
Can superflares occur on the Sun? A view from dynamo theory
M. M. Katsova, L. L. Kitchatinov, M. A. Livshits +3
Recent data from the Kepler mission has revealed the occurrence of superflares in sun-like stars which exceed by far any observed solar flares in release of energy. A natural idea…
Heliospheric modulation of cosmic rays during the neutron monitor era: Calibration using PAMELA data for 2006--2010
Ilya G. Usoskin, Agnieszka Gil, Gennady A. Kovaltsov +2
A new reconstruction of the heliospheric modulation potential for galactic cosmic rays is presented for the neutron monitor era, since 1951. The new reconstruction is based on an u…
Atmospheric ionization induced by precipitating electrons: Comparison of CRAC:EPII model with parametrization model
A. A. Artamonov, A. L. Mishev, I. G. Usoskin
A new model CRAC:EPII (Cosmic Ray Atmospheric Cascade: Electron Precipitation Induced Ionization) is presented. The CRAC:EPII is based on Monte Carlo simulation of precipitating el…
Solar surface rotation: N-S asymmetry and recent speed-up
L. Zhang, K. Mursula, I. Usoskin
Context. The relation between solar surface rotation and sunspot activity still remains open. Sunspot activity has dramatically reduced in solar cycle 24 and several solar activity…
