TL;DR: The optically dark globule IC 1396A is revealed using Spitzer Space Telescope images at 3.6, 4.5, 5.8, 8, and 24 μm to be infrared-bright and to contain a set of previously unknown protostars.

TL;DR: In this paper, the bolometric luminosities and temperatures for 330 Orion YSOs, 315 of which have bolometric temperatures characteristic of protostars, were analyzed using fits to the spectral energy distributions (SEDs).

TL;DR: In this article, the Spitzer Space Telescope observations of the young cluster NGC2264 have been used to identify the most highly embedded and youngest objects in the cluster, and the majority of these sources are found to be protostellar in nature with Class I spectral energy distributions.

TL;DR: The first definitive detection of disk accretion in an object near or below the substellar limit was made in this paper, where the authors obtained an echelle-resolution spectrum of the very low mass T Tauri star V410 Anon 13; the emission-line profile of Hα clearly exhibits the large line width and asymmetry characteristic of a freefalling accretion flow.

TL;DR: In this paper, a proper motion survey of pre-main-sequence stars near the Taurus-Auriga molecular cloud is presented, with 209 possible Taurus proper motion members selected from an initial sample of 4600 stars with V ≥ 16 in a 8.9 square degree region.
