An analysis of full disc line of sight velocity data yield line splitting values of the low l-value non-radial modes. Possible variations of the line splitting...
Infrared and V band photometry of the RS CVn system II Peg, carried out in 1984 and 1986, has been analysed with a simple model in order to follow the evolution...
This first part of Special Session 5 explored the current status of infrared-based observations of obscured and distant stellar clusters in the Milky Way galaxy...
SS Cygni - The mass accretion rate behaviour in quiescence and in outburst
The correspondent mass accretion rate values for SS Cygni are deduced from the He II 1640 A emission line equivalent width values in all good available IUE low...
SS433 and the nature of ultra-luminous X-ray sources
The nature of the ultra-luminous X-ray sources (ULXs) discovered in significant numbers in nearby galaxies by XMM and CXO continues to be a controversial topic...
SS433 is the prototype microquasar in the Galaxy and may even be analogous to the ULX sources if the jets' kinetic energy is taken into account. However, in...
