Peculiarities of the UV Continuum Energy Distribution for T Tauri Stars
Lamzin, S. A.; Kravtsova, A. S.
In the UV spectra of BP Tau, GW Ori, T Tau, and RY Tau obtained with the Hubble Space Telescope, we detected an inflection near 2000 Angstrems in the F^clambda(lambda) curve that describes the continuum energy distribution. The inflection probably stems from the fact that the UV continuum in these stars consists of two components: the e…
Estimating the Interstellar Extinction and the Contribution from an Accretion Shock to the Formation of Emission Continuum in DS Tau and DG Tau
Kravtsova, A. S.
We analyze the UV spectra of the young stars DG Tau and DS Tau taken with the STIS spectrograph from the Hubble Space Telescope. For these stars, we found the upper limits of the interstellar extinction A_V. Their values proved to be lower than those obtained by other authors from optical observations. For DS Tau, DG Tau, and TW Hya, we also deter…
