Accretion in brown dwarfs: An infrared view
This paper presents a study of the accretion properties of 19 very low mass objects ($M_\star$~ $0.01{-}0.1$ $M_\odot$) in the regions Chamaeleon I and ρ  Oph. For 8 objects we obtained highExpand
Passive Irradiated Circumstellar Disks with an Inner Hole
A model for irradiated dust disks around Herbig Ae stars is proposed. The model is based on the flaring disk model given by Chiang and Goldreich in 1997, but with the central regions of the diskExpand
Accretion in the ρ-Ophiuchi pre-main sequence stars
Aims. The aim of this paper is to provide a measurement of the mass accretion rate in a large, complete sample of objects in the core of the star forming region p Oph. Methods. The sample includesExpand
Accretion Rates in Herbig Ae stars
Aims. Accretion rates from disks around pre-main sequence stars are of importance for our understanding of planetary formation and disk evolution. We provide in this paper estimates of the massExpand
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
ALMA Survey of Lupus Protoplanetary Disks. I. Dust and Gas Masses
We present the first high-resolution sub-millimeter survey of both dust and gas for a large population of protoplanetary disks. Characterizing fundamental properties of protoplanetary disks on aExpand
H2 and CO Emission from Disks around T Tauri and Herbig Ae Pre-Main-Sequence Stars and from Debris Disks around Young Stars: Warm and Cold Circumstellar Gas*
We present ISO Short-Wavelength Spectrometer observations of H_2 pure-rotational line emission from the disks around low- and intermediate-mass pre-main-sequence stars as well as from young starsExpand
Ringed Structures of the HD 163296 Protoplanetary Disk Revealed by ALMA.
TLDR
From the measurements of the dust and gas densities, it is deduce that the gas-to-dust ratio varies across the disk and, in particular, it increases by at least a factor 5 within the inner dust gap compared to adjacent regions of the disk. Expand
The shape of the inner rim in proto-planetary disks
We discuss the properties of the inner puffed-up rim that forms in circumstellar disks when dust evaporates. We argue that the rim shape is controlled by a fundamental property of circumstellarExpand
Dust grain growth in ρ-Ophiuchi protoplanetary disks
We present new ATCA observations at 3.3 mm of 27 young stellar objects in the ρ-Oph young cluster. 25 of these sources have been detected. We analyze the sub-millimeter and millimeter SED for aExpand
