Behind the Mask: can HARMONI@ELT detect biosignatures in the reflected light of Proxima b?

Sophia R. Vaughan, Jayne L. Birkby, Niranjan Thatte +7

Proxima b is a rocky exoplanet in the habitable zone of the nearest star system and a key test case in the search for extraterrestrial life. Here, we investigate the characterizati…

Direct imaging and spectroscopy of exoplanets with the ELT/HARMONI high-contrast module

Mathis Houllé, Arthur Vigan, Alexis Carlotti +9

Combining high-contrast imaging with medium-resolution spectroscopy has been shown to significantly boost the direct detection of exoplanets. HARMONI, one of the first-light instru…

Imaging low-mass planets within the habitable zone of α Centauri

K. Wagner, A. Boehle, P. Pathak +39

Giant exoplanets on wide orbits have been directly imaged around young stars. If the thermal background in the mid-infrared can be mitigated, then exoplanets with lower masses can…
