SuperCam: a 64-pixel heterodyne imaging array for the 870-micron atmospheric window (Proceedings Paper)
Heterodyne imaging arrays submillimeter molecular spectroscopy
2014/12/23
We report on the development of SuperCam, a 64 pixel, superheterodyne camera designed for operation in the astrophysically important 870 μm atmospheric window. SuperCam will be used to answer fundamen...
Temperature-Pressure Profile of the hot Jupiter HD 189733b from HST Sodium Observations: Detection of Upper Atmospheric Heating
spectroscopic planetary systems individual HD 189733b
2012/2/23
We present transmission spectra of the hot Jupiter HD 189733b taken with the Space Telescope Imaging Spectrograph aboard HST. The spectra cover the wavelength range 5808-6380 Ang with a resolving powe...
The hot-Jupiter Kepler-17b: discovery, obliquity from stroboscopic starspots, and atmospheric characterization
hot-Jupiter Kepler-17b discovery stroboscopic starspots atmospheric characterization
2011/10/20
This paper reports the discovery and characterization of the transiting hot giant exoplanet Kepler-17b. The planet has an orbital period of 1.486 days, and radial velocity measurements from the Hobby-...
Dynamical Opacity-Sampling Models of Mira Variables. II: Time-Dependent Atmospheric Structure and Observable Properties of 4 M-Type Model Series
stars: AGB and post-AGB, stars: atmospheres, stars: variables: other, stars: mass loss
2011/10/11
We present 4 model series of the CODEX dynamical opacity-sampling models of Mira variables with solar abundances, designed to have parameters similar to $o$ Cet, R Leo and R Cas. We demonstrate that t...
Near-infrared thermal emissivity from ground based atmospheric dust measurements at ORM
Site testing – Methods: data analysis – Methods: statistical
2011/9/30
We present an analysis of the atmospheric content of aerosols measured at Observatorio del Roque de los Muchachos (ORM; Canary Islands). Using a laser diode particle counter located at the Telescopio ...
The observation of astrophysical neutrinos requires a detailed understanding of the atmospheric neutrino background. Since neutrinos are produced in meson decays together with a charged lepton, import...
Thermohaline Mixing: Does It Really Govern the Atmospheric Chemical Composition of Low-Mass Red Giants?
stars abundances — stars evolution — stars interiors
2010/11/12
First results of our 3D numerical simulations of thermohaline convection driven by 3He burning in a low-mass RGB star at the bump luminosity are presented. They confirm our previous conclusion that th...
A Site Evaluation Campaign for a Ground Based Atmospheric Cherenkov Telescope in Romania

2010/11/15
Around the world, several scientific projects share the interest of a global network of small Cherenkov telescopes for monitoring observations of the brightest blazars - the DWARF network. A small, gr...
Towards Precision LSST Weak-Lensing Measurement - I: Impacts of Atmospheric Turbulence and Optical Aberration
Astronomical Instrumentation gravitational lensing dark matter cosmology
2010/11/12
The weak-lensing science of the Large Synoptic Survey Telescope (LSST)project drives the need to carefully model and separate the instrumental arti-facts from the intrinsic shear signal caused by grav...
High-energy atmospheric neutrinos
High Energy Astrophysical Phenomena (astro-ph.HE) High Energy Physics - Experiment (hep-ex)
2010/12/29
High-energy neutrinos, arising from decays of mesons that were produced through the cosmic rays collisions with air nuclei, form unavoidable background noise in the astrophysical neutrino detection pr...
An Advanced Atmospheric Dispersion Corrector: The Magellan Visible AO Camera
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/27
In addition to the BLINC/MIRAC IR science instruments, the Magellan adaptive secondary AO system will have an EEV CCD47 that can be used both for visible AO science and as a wide-field acquisition cam...
Atmospheric circulation of tidally-locked exoplanets: a suite of benchmark tests for dynamical solvers
Earth and Planetary Astrophysics (astro-ph.EP) Galaxy Astrophysics (astro-ph.GA)
2010/12/27
The complexity of atmospheric modelling and its inherent non-linearity, together with the limited amount of data of exoplanets available, motivate model intercomparisons and benchmark tests.
Binary Contamination in the SEGUE sample: Effects on SSPP Determinations of Stellar Atmospheric Parameters
