Title: The Ring Nebula Around the Blue Supergiant SBW1: Pre-Explosion Snapshot of a SN 1987A Twin Authors: Nathan Smith, W. David Arnett, John Bally, Adam Ginsburg, Alexei V. Filippenko SBW1 is a B supergiant surrounded by a ring nebula that is a nearby twin of SN 1987A. We present images and spectra...
Title: Alfvén Reflection and Reverberation in the Solar Atmosphere Authors: P. S. Cally Magneto-atmospheres with Alfvén speed [a] that increases monotonically with height are often used to model the solar atmosphere, at least out to several solar radii. A common example involves uniform verti...
