Oxygen and nitrogen abundances in Virgo and field spirals
L. S. Pilyugin, Mercedes Molla, Federico Ferrini +1
The oxygen and nitrogen abundances in the HII regions of the nine Virgo spirals of the sample from Skillman et al (1996) and in nine field spiral galaxies are re-determined with th…
The influence of dynamic tides on the apsidal-motion rate in close binaries with an evolved main-sequence star
B. Willems, A. Claret
The validity of the classical formula for the rate of secular apsidal motion in close binaries is investigated for a sequence of models of a 5 solar mass star ranging from the last…
The Parker Instability in 3-D: Corrugations and Superclouds Along the Carina-Sagittarius Arm
Jose Franco, Jongsoo Kim, Emilio J. Alfaro +1
Here we present three-dimensional MHD models for the Parker instability in a thick magnetized disk, including the presence of a spiral arm. The -field is assumed parallel to the…
Strategies for prompt searches for GRB afterglows: the discovery of the GRB 001011 optical/near-infrared counterpart using colour-colour selection
J. Gorosabel, J. U. Fynbo, J. Hjorth +25
We report the discovery of the optical and near-infrared counterparts to GRB 001011. The GRB 001011 error box determined by Beppo-SAX was simultaneously imaged in the near-infrared…
A Multiwavelength Study of Stephan's Quintet
Jack W. Sulentic, M. Rosado, D. Dultzin-Hacyan +4
Stephan's Quintet (SQ) is a compact group that we find in an atypical moment when a high velocity intruder is passing through it. The intrusion is particularly interesting because…
75 kpc trails of ionized gas behind two Irr galaxies in A1367
G. Gavazzi, A. Boselli, L. Mayer +3
In a 6h Halpha exposure of the N-W region of the cluster of galaxies A1367 we discovered a 75 kpc cometary emission of ionized gas trailing behind two Irregular galaxies. The Halph…
