A Filament-Associated Halo Coronal Mass Ejection
Zhang, Jun; Wang, Jingxiu; Nitta, Nariaki
There are only a few observations published so far that show the initiation of a coronal mass ejection (CME) and illustrate the magnetic changes in the surface origin of a CME. Any attempt to connect a CME with its local solar activities is meaningful. In this paper we present a clear instance of a halo CME initiation. A careful analysis of magnet…
Infall and Outflow Activities in the Be star FY CMa
Cao, Hui-Lai
Unusual activity of outflow mass motion connected with infall events was recorded for the B0.5 IVe star FY CMa in February 1987 from both archival IUE spectrograms of circumstellar N resonance lines and optical spectra of Hα and He λ5876 Å emission lines which showed inverse P Cygni-type profiles. We estimate the mass loss rate using ultraviolet S…
