Spectro-photometry of Phobos simulants: I. Detectability of hydrated minerals and organic bands
Antonin Wargnier, Thomas Gautier, Alain Doressoundiram +12
Previous observations of Phobos and Deimos, the moons of Mars, have improved our understanding of these small bodies. However, their formation and composition remain poorly constra…
Phobos photometric properties from Mars Express HRSC observations
S. Fornasier, A. Wargnier, P. H. Hasselmann +5
This study aims to analyze Phobos' photometric properties using Mars Express mission observations to support the Martian Moons eXploration mission. We analyzed resolved images of P…
Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations
J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…
GravityCam: Wide-field Imaging Surveys in the Visible from the Ground
C. Mackay, M. Dominik, I. A. Steele +13
GravityCam is a new concept of ground-based imaging instrument capable of delivering significantly sharper images from the ground than is normally possible without adaptive optics.…
Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016
E. Meza, B. Sicardy, M. Assafin +167
Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by th…
A spectroscopic survey of the small near-Earth asteroid population: peculiar taxonomic distribution and phase reddening
Davide Perna, Maria Antonietta Barucci, Marcello Fulchignoni +6
We present the results of the first-ever visible spectroscopic survey fully dedicated to the small (absolute magnitude H>20) near-Earth asteroid (NEA) population. Observations have…
Olivine-rich asteroids in the near-Earth space
M. Popescu, D. Perna, M. A. Barucci +6
In the framework of a 30-night spectroscopic survey of small near-Earth asteroids (NEAs) we present new results regarding the identification of olivine-rich objects. The following…
Rotationally-resolved spectroscopy of Jupiter Trojans (624) Hektor and (911) Agamemnon
Davide Perna, Nicolas Bott, Tetiana Hromakina +3
We present the first-ever rotationally resolved spectroscopic investigation of (624) Hektor and (911) Agamemnon, the two largest Jupiter Trojans. The visible and near-infrared spec…
GravityCam: Wide-Field High-Resolution High-Cadence Imaging Surveys in the Visible from the Ground
C. Mackay, M. Dominik, I. A. Steele +13
GravityCam is a new concept of ground-based imaging instrument capable of delivering significantly sharper images from the ground than is normally possible without adaptive optics.…
Rotational properties of the Haumea family members and candidates: Short-term variability
Audrey Thirouin, Scott S. Sheppard, Keith S. Noll +3
Haumea is one of the most interesting and intriguing transneptunian objects (TNOs). It is a large, bright, fast rotator, and its spectrum indicates nearly pure water ice on the sur…
Pluto's atmosphere from stellar occultations in 2012 and 2013
A. Dias-Oliveira, B. Sicardy, E. Lellouch +42
We analyze two multi-chord stellar occultations by Pluto observed on July 18th, 2012 and May 4th, 2013, and monitored respectively from five and six sites. They provide a total of…
Reanalyzing the visible colors of Centaurs and KBOs: what is there and what we might be missing
Nuno Peixinho, Audrey Delsanti, Alain Doressoundiram
Visible colors (BVRI) are a reasonable proxy for real spectra of Centaurs and Kuiper Belt Objects, which are rather linear in this range. Colors provide limited information but rem…
"TNOs are Cool": A survey of the trans-Neptunian region I. Results from the Herschel Science Demonstration Phase (SDP)
T. G. Mueller, E. Lellouch, J. Stansberry +32
The goal of the Herschel Open Time Key programme "TNOs are Cool!" is to derive the physical and thermal properties for a large sample of Centaurs and trans-Neptunian objects (TNOs)…
Colors and taxonomy of Centaurs and Trans-Neptunian Objects
D. Perna, M. A. Barucci, S. Fornasier +6
The study of the surface properties of Centaurs and Trans-Neptunian Objects (TNOs) provides essential information about the early conditions and evolution of the outer Solar System…
Visible spectroscopy of the new ESO Large Program on trans-Neptunian objects and Centaurs: final results
S. Fornasier, M. A. Barucci, C. de Bergh +8
A second large programme (LP) for the physical studies of TNOs and Centaurs, started at ESO Cerro Paranal on October 2006 to obtain high-quality data, has recently been concluded.…
Reopening the TNOs Color Controversy: Centaurs Bimodality and TNOs Unimodality
N. Peixinho, A. Doressoundiram, A. Delsanti +3
We revisit the Trans-Neptunian Objects (TNOs) color controversy allegedly solved by Tegler and Romanishin 2003. We debate the statistical approach of the quoted work and discuss wh…
