Age Estimation and Mass Functions of Ttauri Stars in the Taurus Auriga Molecular Cloud
نویسنده
چکیده
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 M 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 × 10 yr and the mass function is about 0.644∓0.348. From these results, we have calculated the stellar birthrate as about 1.3 × 10 M yr −1 in this region.

High resolution spectroscopy of Brown Dwarfs in Taurus
We present high resolution optical spectroscopy of three candidate members of the Taurus-Auriga star forming region. Based on the spectral type, the strength, profile and width of the Hα line, the detected lithium at 6708 Å, the location of these objects in a H-R diagram and the comparison with similar objects belonging to young stellar associations, we determine that they are bona fide members...
متن کاملA 1.3mm dust continuum survey of Hα selected TTauri stars in Lupus
Wehave observed a sample of 32Hα selectedTTauri stars in theLupus 2 and3T associationwith the facility bolometer at the SEST and detected cold dust emission at 1.3mm from 12 of the objects. For the remaining objects we have derived 3σ upper limits (≈ 40mJy),which suggest that the cold dustmasses are less than 5 · 10−5 M . For stellar masses below 0.7M the mean disk mass (gas + dust) is approxim...
متن کاملOptical Spectroscopy of Embedded Young Stars in the Taurus-Auriga Molecular Cloud
This paper describes the first optical spectroscopic survey of class I sources (also known as embedded sources and protostars) in the Taurus-Auriga dark cloud. We detect 10 of the 24 known class I sources in the cloud at 5500–9000 Å. All detected class I sources have strong Hα emission; most also have strong [O I] and [S II] emission. These data – together with high quality optical spectra of T...
متن کاملOnthe Alignment of Ttauri Stars with the Local Magnetic Field
Magnetic field is believed to play an important role in the collapse of a molecular cloud. In particular, due to the properties of magnetic forces, collapse should be easier along magnetic field lines, as supported by the large-scale sheet-like structure of the Taurus giant molecular cloud for instance. Here we investigate whether such a prefered orientation for collapse is present at a much sm...
متن کاملB- and A-type Stars in the Taurus-auriga Star Forming Region
We describe the results of a search for early-type stars associated with the Taurus-Auriga molecular cloud complex, a diffuse nearby star-forming region noted as lacking young stars of intermediate and high mass. We investigate several sets of possible O, B and early A spectral class members. The first is a group of stars for which mid-infrared images show bright nebulae, all of which can be as...
