The discovery of large numbers of young low-mass stars and brown dwarfs over the past
decade has made it possible to investigate star formation and early evolution in a previously …

We report the statistical properties of stars, brown dwarfs and multiple systems obtained from
the largest radiation hydrodynamical simulation of star cluster formation to date that resolves …

Context. The physical properties of almost any kind of astronomical object can be derived by
fitting synthetic spectra or photometry extracted from theoretical models to observational …

We have analyzed nearly all images of the Taurus star-forming region at 3.6, 4.5, 5.8, 8.0,
and 24 μm that were obtained during the cryogenic mission of the Spitzer Space Telescope …

Low-resolution spectra from 3000 to 9000 Å of young low-mass stars and brown dwarfs
were obtained with LRIS on Keck I. The excess UV and optical emission arising in the …

We present a uniform analysis of all mid-infrared R≈ 90 spectra of field M5–T9 dwarfs
obtained with the Spitzer Infrared Spectrograph (IRS). The sample contains 113 spectra out …

We have refined the census of stars and brown dwarfs in the Upper Sco association (∼ 10
Myr,∼ 145 pc) by (1) updating the selection of candidate members from our previous survey …

ABSTRACT We present 161 Spitzer Infrared Spectrograph (IRS) spectra of T Tauri stars and
young brown dwarfs in the Taurus star-forming region. All of the targets were selected based …

We have obtained optical and near-infrared spectra of candidate members of the star-
forming clusters IC 348 and NGC 1333. We classify 100 and 42 candidates as new …

We report the discovery of three planetary-mass companions (M= 6–20 M Jup) in wide orbits
(ρ∼ 150–300 AU) around the young stars FW Tau (Taurus-Auriga), ROXs 12 (Ophiuchus) …
