On external shock model to explain the high-energy emission: GRB 940217, GRB 941017 and GRB 970217A
N. Fraija, M. M. Gonzalez, J. L. Ramirez +2
We present a leptonic model on the external shock context to describe the high-energy emission of GRB 940217, GRB 941017 and GRB 970217A. We argue that the emission consists of two…
GRB980923. A burst with a short duration high energy component
M. M. Gonzalez, J. R. Sacahui, J. L. Ramirez +2
The prompt emission of Gamma Ray Bursts (GRBs) is usually well described by the Band function: two power-laws joined smoothly at a given break energy. In addition to the Band compo…
Toroidal versus poloidal magnetic fields in Sun-like stars: a rotation threshold
P. Petit, B. Dintrans, S. K. Solanki +8
From a set of stellar spectropolarimetric observations, we report the detection of surface magnetic fields in a sample of four solar-type stars, namely HD 73350, HD 76151, HD 14623…
Magnetism in Herbig Ae/Be stars and the link to the Ap/Bp stars
E. Alecian, C. Catala, G. A. Wade +11
Among the A/B stars, about 5% host large-scale organised magnetic fields. These magnetic stars show also abundance anomalies in their spectra, and are therefore called the magnetic…
Magnetism in pre-MS intermediate-mass stars and the fossil field hypothesis
E. Alecian, G. A. Wade, C. Catala +11
Today, one of the greatest challenges concerning the Ap/Bp stars is to understand the origin of their slow rotation and their magnetic fields. The favoured hypothesis for the latte…
