Effects of mass loss for highly-irradiated giant planets
W. B. Hubbard, M. F. Hattori, A. Burrows +2
We present calculations for the evolution and surviving mass of highly-irradiated extrasolar giant planets (EGPs) at orbital semimajor axes ranging from 0.023 to 0.057 AU using a g…
Searching for White and Brown Dwarfs in the frame of the MUSYC/CYDER survey
M. Altmann, R. A. M'endez, M. -T. Ruiz +4
MUSYC (MUltiwavelength Survey by Yale and Chile), and its predecessor, the CYDER (Cal'an Yale Deep Extragalactic Research) survey are both deep multiwavelength surveys mainly aimin…
Spectral Analysis of Super Soft X-ray Sources: V4743 Sagittarii
Thomas Rauch, Marina Orio, R. Gonzales-Riestra +1
Half a year after its outburst, the nova V4743 Sgr evolved into the brightest super-soft X-ray source in the sky with a flux maximum around 30A, exhibiting resonance lines of C V,…
Gamma-ray bursts from alternating-current jets
M. Sikora, M. C. Begelman, P. Coppi +1
We propose a gamma-ray burst scenario involving relativistic jets dominated by Poynting flux with alternating toroidal magnetic fields. Such a structure may arise naturally if the…
The Enigma of Lithium: from CP Stars to K Giants. First Results of CP Star Observations Obtained at Mount Stromlo Observatory
N. S. Polosukhina, N. A. Drake, M. Hack +3
We present the results of the observations of some roAp stars made at Mount Stromlo Observatory during 17 nights in 2001 September-October. This long observing run permitted us to…
Bulge formation in very late-type galaxies
YanNing Fu, JieHao Huang, ZuGan Deng
The dynamical evolution of super star clusters (SSCs) moving in the background of a dark matter halo has been investigated as a possible event responsible for the formation of bulg…
