Spectral energy distributions are presented for 94 young stars surrounded by disks in the Serpens Molecular Cloud, based on photometry and Spitzer/IRS spectra. Most of the stars have spectroscopically determined spectral types. Taking a distance to the cloud of 415 pc rather than 259 pc, the distribution of ages is shifted to lower values, in the 1–3 Myr range, with a tail up to 10 Myr. The mass distribution spans 0.2–1.2 M☉, with median mass of 0.7 M☉. The distribution of fractional disk… 

An SMA Continuum Survey of Circumstellar Disks in the Serpens Star-forming Region

We present observations with the Submillimeter Array of the continuum emission at from 62 young stars surrounded by a protoplanetary disk in the Serpens star-forming region. The typical angular

NEW X-RAY-SELECTED PRE-MAIN-SEQUENCE MEMBERS OF THE SERPENS MOLECULAR CLOUD

The study of young stars no longer surrounded by disks can greatly add to our understanding of how protoplanetary disks evolve and planets form. We have used VLT/FLAMES optical spectroscopy to

AN OPTICAL SPECTROSCOPIC STUDY OF T TAURI STARS. I. PHOTOSPHERIC PROPERTIES

Estimates of the mass and age of young stars from their location in the H-R diagram are limited by not only the typical observational uncertainties that apply to field stars, but also by large

Imaging the circumstellar environment of the young T Tauri star SU Aurigae

The circumstellar environments of classical T Tauri stars are challenging to directly image because of their high star-to-disk contrast ratio. One method to overcome this is by using imaging

Identifying gaps in flaring Herbig Ae/Be disks using spatially resolved mid-infrared imaging - Are all group I disks transitional?

Context. The evolution of young massive protoplanetary disks toward planetary systems is expected to correspond to structural changes in observational appearance, which includes the formation of gaps

The (w)hole survey: An unbiased sample study of transition disk candidates based on Spitzer catalogs

Understanding disk evolution and dissipation is essential for studies of planet formation. Transition disks, i.e., disks with large dust cavities and gaps, are promising candidates of active

Spectroscopic characterization of X-ray emitting young stars associated with the Sh 2-296 nebula

We studied a sample of stars associated with the Sh 2-296 nebula, part of the reflection nebulae complex in the region of Canis Major (CMa R1). Our sample corresponds to optical counterparts of X-ray

Census of Variable Stars toward Serpens Main

We monitored a 3 deg2 area toward Serpens Main in the Pan-STARRS1 r, i, and z bands from 2016 April to September. Light curves of more than 11,000 stars in each band were obtained, and 143 variables

Identification of Young Stellar Object candidates in the Gaia DR2 x AllWISE catalogue with machine learning methods

An all-sky probabilistic catalogue of Young Stellar Objects (YSOs) is made and the 3D structure of the Orion A star-forming complex is explored and the spatial distribution of the YSOs classified by the procedure is in agreement with recent results from the literature.

Soft X-ray Irradiation of Silicates: Implications on Dust Evolution in Protoplanetary Disks

The processing of energetic photons on bare silicate grains was simulated experimentally on silicate films submitted to soft X-rays of energies up to 1.25 keV. The silicate material was prepared by

Context. Dust particles evolve in size and lattice structure in protoplanetary disks, due to coagulation, fragmentation and crystallization, and are radially and vertically mixed in disks due to
