A FIRST CONSTRAINT ON THE THICK DISK SCALE LENGTH: DIFFERENTIAL RADIAL ABUNDANCES IN K GIANTS AT GALACTOCENTRIC RADII 4, 8, AND 12 kpc
(IOP PUBLISHING LTD, 2011)
Based on high-resolution spectra obtained with the MIKE spectrograph on the Magellan telescopes, we present detailed elemental abundances for 20 red giant stars in the outer Galactic disk, located at Galactocentric distances ...
Precession of neutrino-cooled accretion disks in gamma-ray burst engines
(EDP Sciences, 2006-07)
Aims. We study the precession of accretion disks in the context of gamma-ray burst inner engines. Methods. With an accretion disk model that allows for neutrino cooling, we evaluate the possible periods of disk precession ...

Predicting the kinematic evidence of gravitational instability
(IOP Publishing, 2020)
Observations with the Atacama Large Millimeter/Submillimeter Array (ALMA) have dramatically improved our understanding of the site of exoplanet formation: protoplanetary disks. However, many basic properties of these disks ...
Gas Inside the 97 AU Cavity around the Transition Disk Sz 91
(The American Astronomical Society, 2015-05-20)
We present ALMA (Cycle 0) band 6 and band 3 observations of the transition disk Sz 91. The disk inclination and
position angle are determined to be i = 49◦
. 5 ± 3◦
. 5°and PA = 18◦

Planet Formation Signposts: Observability of Circumplanetary Disks via Gas Kinematics
(The American Astronomical Society, 2015-09-20)
The identification of ongoing planet formation requires the finest angular resolutions and deepest sensitivities in
observations inspired by state-of-the-art numerical simulations. Hydrodynamic simulations of planet–dis ...
Tomographic Simulations of accretion disks in cataclysmic variables - Flickering and wind
(ASTRONOMICAL SOC JAPAN, 2008)
Both continuum and emission line flickering are phenomena directly associated with the mass-accretion process. In this work we simulated accretion-disk Doppler maps, including the effects of winds and flickering flares. ...
Determination of Hormones in Wastewater Using Rotating Disk Sorptive Extraction and Gas Chromatography-Mass Spectrometry
(Taylor & Francis, 2016)
A simple and green analytical method based on the use of rotating disk sorptive extraction is reported for the simultaneous determination of hormones in wastewater. The analytes were 17-estradiol, estriol, and 17 ...
