Extended Near-infrared Emission from Candidate Protostars in the Taurus-auriga Molecular Cloud
نویسندگان
چکیده
We describe near-IR imaging data for a sample of 23 Class I sources in the Taurus-Auriga dark clouds. Combining our data with previous photometry, we detect brightness variations of 0.1–0.5 mag in many sources. The near-IR morphologies are consistent with millimeter continuum measurements. Most ( 60%) of the sample are true protostars; the rest may be objects in transition between Class I and Class II, T Tauri stars with edge-on disks, or heavily reddened T Tauri stars.

Optical 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 کاملNew Pre-Main Sequence Candidates in the Taurus-Auriga Star Forming Region
Aims. We have studied the X-ray source population of the Taurus Molecular Cloud (TMC) to search for new members of the Taurus-Auriga star forming region. Methods. Candidate members have been selected among the X-ray sources detected in 24 fields of the XMM-Newton Extended Survey of the Taurus Molecular Cloud, having an IR counterpart in the 2MASS catalog, based on color-magnitude and color-colo...
متن کاملA Three Micron Survey of the Chamaeleon I Dark Cloud
We describe an L-band photometric survey of ∼ 0.5 deg2 of the Cha I dark cloud. The survey has a completeness limit of L < 11.0. Our survey detects 124 sources, including all known pre-main sequence stars with L ≤ 11. The fraction of sources with near-IR excess emission is 58% ± 4% for K = 9–11. Cha I sources have bluer H −K and K − L colors than pre-main sequence stars in Taurus-Auriga. These ...
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...
متن کاملA Distributed Population of Low Mass Pre-main Sequence Stars near the Taurus Molecular Clouds
We present a drift scan survey covering a ∼5 × 50 region toward the Southern portion of the Taurus-Auriga molecular cloud. Data taken in the B,R, I filters with the Quest-2 camera on the Palomar 48-inch telescope were combined with 2MASS near-infrared photometry to select candidate young stars. Follow-up optical spectroscopy of 190 candidates led to identification of 42 new low mass pre-main se...
