Observing the linked depletion of dust and CO gas at 0.1–10 au in disks of intermediate-mass stars
(EDP Sciences, 2018)
We report on the discovery of correlations between dust and CO gas tracers of the 0.1–10 au region in planet-forming disks around
young intermediate-mass stars. The abundance of refractory elements on stellar photospheres ...
Accretion Kinematics Through The Warped Transition Disk in HD 142527 From Resolved CO(6–5) Observations
(The American Astronomical Society, 2015-10-01)
The finding of residual gas in the large central cavity of the HD 142527 disk motivates questions regarding the
origin of its non-Keplerian kinematics and possible connections with planet formation. We aim to understand ...
Accretion kinematics through the warped transition disk in hd142527 from resolved CO(6-5) observations
(IOP Publishing, 2015)
The finding of residual gas in the large central cavity of the HD 142527 disk motivates questions regarding the origin of its non-Keplerian kinematics and possible connections with planet formation. We aim to understand ...
The viscosity parameter's dependence on the profile of the disk scale height
(UNIV CHICAGO PRESS, 2008)
It is shown that, for accretion disks, the height scale is a constant whenever hydrostatic equilibrium and the subsonic turbulence regime hold in the disk. In order to have a variable height scale, processes are needed ...
A new rotating-disk sorptive extraction mode, with a copolymer of divinylbenzene and N-vinylpyrrolidone trapped in the cavity of the disk, used for determination of florfenicol residues in porcine plasma Microextraction Techniques
(Springer Verlag, 2014)
A novel extraction approach was developed based on rotating-disk sorptive extraction (RDSE). In this approach the rotating-disk extraction device consists of a Teflon disk, with a cavity that is loaded with a commercial ...
Variability and dust filtration in the transition disk J160421.7-213028 observed in optical scattered light
(EDP Sciences, 2015)
Context. Protoplanetary disks around young stars are the birth-sites of planets. Spectral energy distributions and direct images of a subset of disks known as transition disks reveal dust-depleted inner cavities. Some of ...
Time-resolved photometry of the young dipper RX J1604.3-2130A Unveiling the structure and mass transport through the innermost disk
(EDP Sciences, 2020)
Context. RX J1604.3-2130A is a young, dipper-type, variable star in the Upper Scorpius association, suspected to have an inclined inner disk, with respect to its face-on outer disk. Aims. We aim to study the eclipses to ...
Evidence for a Circumplanetary Disk around Protoplanet PDS 70 b
(Institute of Physics Publishing, 2019)
© 2019. The American Astronomical Society. All rights reserved.We present the first observational evidence for a circumplanetary disk (CPD) around the protoplanet PDS 70 b, based on a new spectrum in the K-band acquired ...
The dynamically disrupted GAP in HD 142527
(IOP PUBLISHING LTD, 2012-08-01)
The vestiges of planet formation have been observed in debris disks harboring young and massive gaseous giants. The process of giant planet formation is terminated by the dissipation of gas in the protoplanetary disk. The ...
