Pollux: high-resolution precision spectroscopy and polarimetry for the Habitable Worlds Observatory
David Le Mignant, Coralie Neiner, Jean-Claude Bouret +9
Pollux is a high-resolution spectrograph and spectropolarimeter (R from 65000 to 100000) covering a spectral range from 100 nm to 1750 nm, proposed by a European consortium to equi…
Pollux UV & FUV polarimeters: first lab results
Adrien Girardot, Ninon Demelier, Coralie Neiner +6
Pollux is a high-resolution spectropolarimeter proposed by a European consortium for the Habitable Worlds Observatory (HWO). Its design covers a broad spectral range from the far-u…
Pollux: decisions affecting the optical architecture of a high-resolution spectrograph and polarimeter for the Habitable Worlds Observatory
Eduard Muslimov, Luca Fossati, Coralie Neiner +5
POLLUX is a candidate European instrumental contribution to the Habitable Worlds Observatory. It is a high-resolution spectrograph with polarimetric capabilities, covering from the…
Pollux test bench: from NUV to FUV polarimetric measurements
Adrien Girardot, Coralie Neiner, Jean-Michel Reess +2
Pollux is a high-resolution spectropolarimeter proposed by an European consortium for HWO. The current design of Pollux features four spectropolarimetric channels, three of which a…
CASSTOR: a scientific and technology nanosatellite demonstrator for UV spectropolarimetry
Coralie Neiner, Vincent Lapeyrere, Eitan Pechevis +18
In the context of the development of several space mission projects for UV spectropolarimetry at high resolution and over a wide UV wavelength range, such as Arago, Polstar, and Po…
Space UV polarimeters
Coralie Neiner, Adrien Girardot, Jean-Michel Reess
Several space missions are proposed or planned for the coming two decades dedicated or including mid- to high-resolution spectropolarimetry on a wide UV band. This includes the Eur…
JWST/MIRI coronagraphic performances as measured on-sky
A. Boccaletti, C. Cossou, P. Baudoz +16
Characterization of directly imaged exoplanets is one of the most eagerly anticipated science functions of the James Webb Space Telescope. MIRI, the mid-IR instrument has the capab…
The SuperCam Infrared Spectrometer for the Perseverance Rover of the Mars2020 mission
Thierry Fouchet, Jean-Michel Reess, Franck Montmessin +38
We present the Infrared spectrometer of SuperCam Instrument Suite that enables the Mars 2020 Perseverance Rover to study remotely the Martian mineralogy within the Jezero crater. T…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
VUV test of a new polarimeter for spectropolarimetric measurements on board space missions
Maelle Le Gal, Martin Pertenais, Arturo Lopez Ariste +4
High-resolution spectropolarimetry is a useful astronomical technique, in particular to study stellar magnetic fields. It has been extensively used in the past but mostly in the vi…
Static spectropolarimeter concept adapted to space conditions and wide spectrum constraints
Martin Pertenais, Coralie Neiner, Pernelle Bernardi +2
The issues related to moving elements in space and instruments working in broader wavelength ranges lead to a need for robust polarimeters, efficient on a wide spectral domain, and…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
Could Jean-Dominique Cassini see the famous division in Saturn's rings?
Julien Lozi, Jean-Michel Reess, Alain Semery +8
Nowadays, astronomers want to observe gaps in exozodiacal disks to confirm the presence of exoplanets, or even make actual images of these companions. Four hundred and fifty years…
SPICES: Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems
Anthony Boccaletti, Jean Schneider, Wes Traub +28
SPICES (Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems) is a five-year M-class mission proposed to ESA Cosmic Vision. Its purpose is to image and charact…
Current results of the PERSEE testbench: the cophasing control and the polychromatic null rate
Julien Lozi, Frederic Cassaing, Jean-Michel Le Duigou +11
Stabilizing a nulling interferometer at a nanometric level is the key issue to obtain deep null depths. The PERSEE breadboard has been designed to study and optimize the operation…
