Monitoring Naked T-Tauri Stars at Mount Stony Brook

One of the main reasons for refurbishing the telescope was to monittor naked T-Tauri stars from the roof. This stars ( also called nTTs) are young sun like stars that are spotted (just like our sun!). The spots on the nTTS are much larger and longer lasting. When the star rotates, the dark spot regions decrease the amount of light getting to our telescopes. As the spots rotate out of view, the light increases to the normal value. By watching the light increase and decrease, we can measure the rotation rate of the star.

We will be posting some lightcurves and details on some of our stars in the next few weeks.
