The most rapidly rotating He-strong emission line star: HR7355
Th. Rivinius, S. Stefl, R. H. D. Townsend +1
Using archival spectroscopic and photometric data, we searched for massive stars with Balmer-emission consistent with magnetically confined circumstellar material. HR 7355 is a for…
Photomeson production in astrophysical sources
A. Muecke, J. P. Rachen, R. Engel +2
Photomeson production is the main energy loss for relativistic nucleons in dense radiation fields like the cosmic microwave background and the radiation fields in Gamma Ray Bursts…
Update on Atmospheric Neutrinos
M. C. Gonzalez-Garcia
I summarize here the results of a global fit to the full data set corresponding to 535 days of data of the Super-Kamiokande experiment as well as to all other experiments in order…
Diagnostics of a Subsurface Radial Outflow From a Sunspot
D. C. Braun, Y. Fan, C. Lindsey +1
We measure the mean frequencies of acoustic waves propagating toward and away from a sunspot employing a spot-centered Fourier-Hankel decomposition of p-mode amplitudes as measured…
