UV Excess Measures of Accretion onto Young Very Low Mass Stars and Brown Dwarfs
Low-resolution spectra from 3000 to 9000 A of young low-mass stars and brown dwarfs were obtained with LRIS on Keck I. The excess UV and optical emission arising in the Balmer and Paschen continuaExpand
Dust properties of protoplanetary disks in the Taurus-Auriga star forming region from millimeter wavelengths
We present the most sensitive 3 mm-survey to date of protoplanetary disks carried out in the Taurus-Auriga star forming region (average rms of about 0.3 mJy), using the IRAM PdBI. With our highExpand
Six months of multiwavelength follow-up of the tidal disruption candidate asassn-14li and implied tde rates from asas-sn
We present ground-based and Swift photometric and spectroscopic observations of the candidate tidal disruption event (TDE) ASASSN-14li, found at the center of PGC043234 (d ' 90 Mpc) by the All-SkyExpand
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 largeExpand
A steeper than linear disk mass-stellar mass scaling relation
NSF Astronomy & Astrophysics Research Grant [1515392]; National Science Foundation of China [11473005]; Italian Ministero dell'Istruzione, Universita e Ricerca through the grant Progetti PremialiExpand
The Far-Ultraviolet Spectrum of TW Hydrae. I. Observations of H2 Fluorescence
We observed the classical T Tauri star TW Hya with the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope (HST) using the E140M grating, from 1150 to 1700 A, with the E230MExpand
Accretion onto Pre-Main-Sequence Stars
Accretion through circumstellar disks plays an important role in star formation and in establishing the properties of the regions in which planets form and migrate. The mechanisms by whichExpand
The Far-Ultraviolet Spectra of TW Hydrae. II. Models of H2 Fluorescence in a Disk*
We measure the temperature of warm gas at planet-forming radii in the disk around the classical T Tauri star (CTTS) TW Hya by modelling the H2 fluorescence observed in HST/STIS and FUSE spectra.Expand
ACCRETION RATES FOR T TAURI STARS USING NEARLY SIMULTANEOUS ULTRAVIOLET AND OPTICAL SPECTRA
We analyze the accretion properties of 21 low-mass T Tauri stars using a data set of contemporaneous near-UV (NUV) through optical observations obtained with the Hubble Space Telescope ImagingExpand
A Major Asymmetric Dust Trap in a Transition Disk
TLDR
The detection of a dust trap in the disk around the star Oph IRS 48 is reported using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and the difference in distribution of big grains versus small grains/gas can be modeled with a vortex-shaped dust trap triggered by a companion.
