Relative intensities of intercombination lines in ultraviolet spectra of T Tauri stars

Lamzin, S. A.; Gomez de Castro, A. I.

Using the accretion shock wave model (Lamzin 1998), we calculate the relative intensities of the strongest intercombination lines in the range 1200-2000 Angstroms. We make a qualitative comparison of theoretical spectra with IUE low-resolution (~=6 Angstroms) spectra of T Tauri stars. We predict that several intercombination lines can be identifie…

UV spectrophotometry and UBVJHKL photometry of the symbiotic nova V443 Her

Munari, U.; Kolotilov, E. A.; Popova, A. A. +1 more

The photometric UBVJHKL observations of the symbiotic star V443 Her performed during 1994-1997 and its UV spectrum obtained from IUE in October 1991 are presented. Over the last decade of dense photometric observations, the U light curve can be described by a sinusoid with P = 598 days. At the same time, no periodic variations (with P or P/2) have…
