We present spatially resolved mid-infrared spectroscopy of the Class I/flat-spectrum protostellar binary system SVS 20 in the Serpens cloud core. The spectra were obtained with the mid-infrared instrument T-ReCS on Gemini South. SVS 20-South, the more luminous of the two sources, exhibits a mid-infrared emission spectrum peaking near 11.3 μm, while SVS 20-North exhibits a shallow amorphous silicate absorption spectrum with a peak optical depth of τ ~ 0.3. After removal of the line-of-sight… 

Investigating the Nature of Variable Class I and Flat-Spectrum Protostars Using 2-4 μm Spectroscopy

In this study I present new K- and L′-band infrared photometry and 2-4 μm spectra of 10 Class I and flat-spectrum stars forming within the Taurus dark cloud complex. Nine sources have H2 v = 0-1 S(1)

Disks and outflows in CO rovibrational emission from embedded, low-mass young stellar objects

Young circumstellar disks that are still embedded in dense molecular envelopes may differ from their older counterparts, but are historically difficult to study because emission from a disk can be

Grain growth across protoplanetary discs: 10 μm silicate feature versus millimetre slope

Context. Young stars are formed with dusty discs around them. The dust grains in the disc are originally of the same size as interstellar dust, i.e., of the order of 0.1 μm. Models predict that these

Dust in Protoplanetary Disks: Properties and Evolution

We review the properties of dust in protoplanetary disks around optically visible pre-main-sequence stars obtained with a variety of observational techniques, from measurements of scattered light at


We obtained JHK images and low-resolution JH spectra in the embedded young cluster in the Serpens cloud Main core (also known as Serpens North). We determined spectral types (SpT) for fifteen

The onset of X-ray emission in young stellar objects - A Chandra observation of the Serpens star-forming region

Aims. To study the properties of X-ray emission from young stellar objects (YSOs) through their evolution from Class I to Class III and determine whether Class 0 protostars emit X-rays. Methods. A

VLTI/MIDI atlas of disks around low- and intermediate-mass young stellar objects

Context. Protoplanetary disks show large diversity regarding their morphology and dust composition. With mid-infrared interferometry the thermal emission of disks can be spatially resolved, and the


Optical and near-infrared variability is a well-known property of young stellar objects. However, a growing number of recent studies claim that a considerable fraction of them also exhibit

First Fruits of the Spitzer Space Telescope: Galactic and Solar System Studies*

AbstractThe Spitzer Space Telescope, launched in August 2003, is the infrared member of NASA's Great Observatory family. Spitzer combines the intrinsic sensitivity of a cryogenic telescope in space

A Unified, Merger-driven Model of the Origin of Starbursts, Quasars, the Cosmic X-Ray Background, Supermassive Black Holes, and Galaxy Spheroids

We present an evolutionary model for starbursts, quasars, and spheroidal galaxies in which mergers between gas-rich galaxies drive nuclear inflows of gas, producing starbursts and feeding the buried



Mid-infrared Spectra of Class I Protostars in Taurus

We present Spitzer Space Telescope Infrared Spectrograph observations in the 5.3-20 μm range of five young stellar objects in Taurus that have Class I continuum spectral energy distributions (λFλαλn,

Mid-IR spectroscopy of T Tauri stars in Chamealeon I: Evidence for processed dust at the earliest stages

We present mid-IR spectroscopy of three T Tauri stars in the young Chamealeon I dark cloud obtained with TIMMI2 on the ESO 3.6 m telescope. In these three stars, the silicate emission band at 9.7  μ

ISOCAM-CVF spectroscopy of the circumstellar environment of young stellar objects ?

We present the results of a mid-infrared (5-16.5m) imaging spectroscopy survey of Young Stellar Objects (YSOs) and their surrounding environment in four low-mass star formation regions: RCrA,

Subaru K-Band Spectroscopy of Low-Mass Protostars in Taurus

We present K-band spectra of five Class I objects in the Taurus molecular cloud. The high-sensitivity and high-spatial resolution observations using the Subaru Telescope enabled us to detect the

Processing of silicate dust grains in Herbig Ae/Be systems

We have analysed the 10 m spectral region of a sample of Herbig Ae/Be (HAEBE) stars. The spectra are dominated by a broad emission feature caused by warm amorphous silicates, and by polycyclic
