2021/02 - Portion of a SPIRou frame recorded for AU Mic. Each group of three vertical bars corresponds to one spectral order, covering a small region of the spectral domain. The two left-most vertical bars of each order contain the spectrum of AU Mic (in two orthogonal polarization states) whereas the right-most one contains a Fabry-Perot spectrum ensuring that velocimetric variation of the star can be monitored with a precision of a few m/s. The spectral lines (along with telluric lines from the Earth’s atmosphere) show up as darker horizontal bands in the image. These lines form a cosmic barcode encrypting information about AU Mic, its transiting planet and its magnetic activity that the SPIRou team was able to decode for the discovery outlined in this press release (©SPIRou team) — AU Mic planetary system #2

2021/02 - To better understand the formation of stars and their planets, it is key to find out whether the planet’s orbit is tilted to the equatorial plane of its host star. Our new results show that this tilt is small in the case of the giant planet of AU Mic, in agreement with recent models of planetary formation within protoplanetary discs.

2021/02 - The new SPIRou spectrograph / spectropolarimeter, thanks to which our new results were secured, was installed at the Canada-France-Hawaii Telescope in 2018. SPIRou is a cryogenic instrument cooled down at -200°C that needs to be thermally regulated at the extreme stability level of 0.001°C to be able to detect planets like that of AU Mic. © SPIRou team / S Chastanet (CNRS / OMP) — AU Mic planetary system #4

2021/02 - These curves depict the probability of a periodic oscillation to be present in the SPIRou radial velocity (RV) data, for wobble periods ranging from 1 to 50 days. Once the periodic RV signal induced by the activity of the rotating star (at a period of 4.86 day) is corrected for in the raw RV data (upper panel), the periodic signal induced by the newly-detected orbiting planet (at a period of 8.46 day) clearly shows up in the filtered RV data (lower panel) at a confidence level higher than 99.9%. ©B. Klein — AU Mic planetary system #6

`2018`

2018/04/24 - Portion of a SPIRou frame recorded for AD Leo. Each group of three vertical bars corresponds to one spectral order, covering a small region of the overall spectral domain. The two left-most vertical bars of each order contain the spectrum of AD Leo (in two polarization states) whereas the right-most one contains a Fabry-Perot spectrum ensuring that velocimetric variations of the star can be monitored with a precision of 1 m/s or better. The spectral lines of AD Leo (along with telluric lines from the Earth’s atmosphere) show up as darker horizontal bands in the image. These lines form a cosmic barcode encrypting information about AD Leo and its potential planets, that SPIRou will be able decipher. (©SPIRou team) — SPIRou First Light at CFHT #1

2018/04/24 - Small portion of the SPIRou spectrum of the active red dwarf AD Leo as observed (w/ telluric lines, red) and once the telluric spectrum (green) is removed (blue). This illustrates how critical telluric subtraction is to properly identify which lines can tell us some information about the observed star, and the planets potentially orbiting it. Located close to the reddest edge of the SPIRou spectrum, this window, containing a plethora of molecular lines, is key for detecting planets (©J.-F.

2018/04 - Zoom on Fabry-Perot lines, as recorded with SPIRou and its new science-grade H4RG array. Note that each spectrograph order (6 order portions are visible here) comes with three channels, two channels (left and middle) for recording the stellar spectrum (one channel for each of the two orthogonal polarization states) and one channel (right) for recording the reference FP spectrum (to track potential RV shifts within the spectrograph). FP spectra are recorded on all three channels during tests, in order to monitor the instrument RV precision, found to be better than 0.2 m/s rms on timescales of 24 hours (©SPIRou team) — First images with H4RG #2

2018/04 - 2D map of the axial defocus (in µm) of the SPIRou spectra over the H4RG detector, as measured with a Hartmann mask (red / blue orders are on the left / right of the detector).
