T_Tauri_2024-03-09 231400JPEG.jpg

Hello

Last night I captured the spectrum of T Tauri, a faint 9.8 magnitude object for my 6" Celestron SCT. In the profile were emission lines- 6717 A[S ll], 6563 Ao H-alpha, 6364 Ao [O l], 6300 Ao [O l], 4963 Ao Fe ll, 4863 AH-beta, and 4340 Ao H-gamma. T Tau is a pre-main-sequence object that is in transition between being a star shrouded in dust to a main-sequence star. T Tau does not undergo nuclear fusion in its core but shines due to gravitational collapse. The forbidden lines of [O l] and [S ll] indicate extremely low gas densities in its accretion disk. I used a 6" Celestron SCT, an Alpy 600, and an Atik Infinity monochrome camera to capture the spectrum. I used PHD-2 to help capture the 7-600s images of the object, Demetra to do the data reduction, and a Miles A7V star for the instrument response. 

Thanks

Dick
