Monitoring the optical turbulence in the surface layer at Dome C, Antarctica, with sonic anemometers
Eric Aristidi, Jean Vernin, Eric Fossat +11
The optical turbulence above Dome C in winter is mainly concentrated in the first tens of meters above the ground. Properties of this so-called surface layer (SL) were investigated…
Four winters of photometry with ASTEP South at Dome C, Antarctica
N. Crouzet, E. Chapellier, T. Guillot +16
Dome C in Antarctica is a promising site for photometric observations thanks to the continuous night during the Antarctic winter and favorable weather conditions. We developed inst…
Six winters of photometry from Dome C, Antarctica: challenges, improvements, and results from the ASTEP experiment
N. Crouzet, D. Mékarnia, T. Guillot +26
ASTEP (Antarctica Search for Transiting ExoPlanets) is a pilot project that aims at searching and characterizing transiting exoplanets from Dome C in Antarctica and to qualify this…
Thermalizing a telescope in Antarctica: Analysis of ASTEP observations
Tristan Guillot, Lyu Abe, Abdelkrim Agabi +13
The installation and operation of a telescope in Antarctica represent particular challenges, in particular the requirement to operate at extremely cold temperatures, to cope with r…
Typical duration of good seeing sequences at Concordia
Eric Fossat, Eric Aristidi, Karim Agabi +4
Context: The winter seeing at Concordia is essentially bimodal, excellent or quite poor, with relative proportions that depend on altitude above the snow surface. This paper studie…
Photometric quality of Dome C for the winter 2008 from ASTEP South
Nicolas Crouzet, Tristan Guillot, Karim Agabi +13
ASTEP South is an Antarctic Search for Transiting Exo- Planets in the South pole field, from the Concordia station, Dome C, Antarctica. The instrument consists of a thermalized 10…
