Remote sensing survey of altiplano-puna volcanic complex rocks and minerals for planetary analog use
(MDPI, 2022)
The Altiplano-Puna Volcanic Complex (APVC) of the Central Andes is an arid region with extensive volcanism, possessing various geological features comparable to those of other solar system objects. The unique features of ...
A Resolved and Asymmetric Ring of PAHs within the Young Circumstellar Disk of IRS 48
(IOP Publishing, 2017)
For one decade, the spectral type and age of the rho Oph object IRS-48 were subject to debate. and mystery. Modeling its disk with mid-infrared to millimeter observations led to various explanations to account for the ...
Accretion from debris disks onto white dwarfs. Fingering (thermohaline) instability and derived accretion rates
(Edp Sciences, 2013-09)
Context. Recent observations of a large number of DA and DB white dwarfs show evidence of debris disks, which are the remnants of old planetary systems. The infrared excess detected with Spitzer and the lines of heavy ...
Thermal remote sensing from Airborne Hyperspectral Scanner data in the framework of the SPARC and SEN2FLEX projects: an overview
(Copernicus GmbH, 2009)
The AHS (Airborne Hyperspectral Scanner) instrument
has 80 spectral bands covering the visible and near
infrared (VNIR), short wave infrared (SWIR), mid infrared
(MIR) and thermal infrared (TIR) spectral range. The ...
Deep Exploration of Eridani with Keck Ms-band Vortex Coronagraphy and Radial Velocities: Mass and Orbital Parameters of the Giant Exoplanet
(Institute of Physics Publishing, 2019)
We present the most sensitive direct imaging and radial velocity (RV) exploration of Eridani to date. Eridani is an adolescent planetary system, reminiscent of the early solar system. It is surrounded by a prominent and ...
Upper limits for mass and radius of objects around proxima cen from SPHERE/VLT
(Oxford University Press, 2017)
The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Centauri using Spectro-Polarimetric High-contrast ...
Differences between the Pallas collisional family and similarly sized B-type asteroids ?
(EDP Sciences, 2016-07)
Context. B-type asteroids constitute a peculiar spectral class within the C-complex. Previous work has pointed out the difference between the visible geometric albedos of B-types and those of the Pallas collisional family ...
Medium-resolution spectrum of the exoplanet HIP 65426 b
(EDP Sciences, 2021)
Medium-resolution integral-field spectrographs (IFS) coupled with adaptive-optics such as Keck/OSIRIS, VLT/MUSE, or SINFONI are appearing as a new avenue for enhancing the detection and characterization capabilities of ...
Material circunestelar en estrellas de tipo enanas blancas
(2020-03)
Se han descubierto discos de gas en un grupo de enanas blancas con discos de polvo, a través de la detección en sus espectros de lineas de emisión inusuales del triplete de Ca II en 8600 Å. En este contexto, se han obtenido ...
The Ophiuchus DIsc Survey Employing ALMA (ODISEA) – II. The effect of stellar multiplicity on disc properties
(Oxford University Press, 2020)
We present adaptive optics (AO) near-infrared (NIR) observations using VLT/NACO and Keck/NIRC2 of Ophiuchus DIsc Survey Employing ALMA (ODISEA) targets. ODISEA is an ALMA survey of the entire population of circumstellar ...
