KUCUK, I.  e  AKKAYA, I.. Age Estimation And Masss Functions of TTauri Stars in The Taurus Auriga Molecular Cloud. Rev. mex. astron. astrofis [online]. 2010, vol.46, n.1, pp.109-114. ISSN 0185-1101.

In this work the present day mass functions (PDMF) of T-Tauri Stars (TTS) which are in the pre-main sequence (PMS) evolutionary phase of their evolution in the Taurus-Auriga Molecular Cloud Complex have been calculated. For this purpose, by applying our modified stellar evolutionary code, stellar models in the mass range 0.1 - 2.5 are used to determine the mass and age mass of TTS. The obtained mass function is compared with the mass function of Miller & Scalo (1979). The age found for TTS is around 1 - 3 × 10⁶ yr and the mass function is about 0.6440.348. From these results, we have calculated the stellar birthrate as about 1.3 × 10^-7 yr ^-1 in this region.
