Superfluid phases of triplet pairing and rapid cooling of the neutron star in Cassiopeia A

Lev B. Leinson

In a simple model it is demonstrated that the neutron star surface temperature evolution is sensitive to the phase state of the triplet superfluid condensate. A multicomponent trip…

Responsibility of a Filament Eruption for the Initiation of a Flare, CME, and Blast Wave, and its Possible Transformation into a Bow Shock

V. V. Grechnev, A. M. Uralov, I. V. Kuzmenko +3

Multi-instrument observations of two filament eruptions on 24 February and 11 May 2011 suggest the following updated scenario for eruptive flare, CME and shock wave evolution. An i…

Statistical Analysis of Current Helicity and Twist in Solar Active Regions over the Phases of the Solar Cycle Using the Spectro-Polarimeter Data of Hinode

Kenichi Otsuji, Takashi Sakurai, Kirill Kuzanyan

Current helicity and twist of solar magnetic fields are important quantities to characterize the dynamo mechanism working in the convection zone of the Sun. We have carried out a s…

Relationship between the Magnetic Flux of Solar Eruptions and the Ap Index of Geomagnetic Storms

I. M. Chertok, M. A. Abunina, A. A. Abunin +2

Solar coronal mass ejections (CMEs) are main drivers of the most powerful non-recurrent geomagnetic storms. In the extreme-ultraviolet range, CMEs are accompanied by bright post-er…

A Challenging Solar Eruptive Event of 18 November 2003 and the Causes of the 20 November Geomagnetic Superstorm. IV. Unusual Magnetic Cloud and Overall Scenario

V. V. Grechnev, A. M. Uralov, I. M. Chertok +4

The geomagnetic superstorm of 20 November 2003 with Dst = -422 nT, one of the most intense in history, is not well understood. The superstorm was caused by a moderate solar eruptiv…
