SPIRou near-infrared spectropolarimetry of the ultra-hot Jupiter KELT-9b: tentative detection of the planet magnetic field
Alexis Lavail, Florian Debras, David Rogé Royo +23
Exoplanetary magnetic fields govern atmospheric escape and circulation but have eluded detection in close-in planets. In the ultra-hot Jupiter KELT-9b, atmospheric dynamo is predic…
Making sense of the spectral line profiles of Betelgeuse and other Red SuperGiants
A. López Ariste, Q. Pilate, A. Lavail +1
Spectropolarimetry of atomic lines in the spectra of Betelgeuse, and other Red SuperGiants (RSG), presents broad line profiles in linear polarization, but narrow profiles in intens…
Spectroscopic detection of Altair's non-radial pulsations
M. Rieutord, P. Petit, D. Reese +4
Context: Rapid rotation is a common feature of early-type stars but which remains a challenge for the models. The understanding of its effect on stellar evolution is however impera…
Asymmetric shocks in Cyg observed with linear spectropolarimetry
A. López Ariste, B. Tessore, E. S. Carlín +7
Aims: From a coherent interpretation of the linear polarisation detected in the spectral lines of the Mira star Cyg, we derive information about the dynamics of the stellar pho…
A far Ultra-Violet Polarimeter by reflection for Pollux on board LUVOIR
Maelle Le Gal, Arturo Lopez Ariste, Coralie Neiner
The ultra-violet (UV) high-resolution spectropolarimeter Pollux is being studied in Europe under CNES leadership for the LUVOIR space mission. LUVOIR is a projected 15-m telescope…
The solar survey at Pic du Midi: calibrated data and improved images
Laurent Koechlin, Luc Dettwiller, Maurice Audejean +2
At Pic du Midi observatory we carry out a solar survey with images of the photosphere, prominences and corona. This survey, named CLIMSO (CLIchés Multiples du SOleil), is in the fo…
