Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) VI. Non-detection of sodium with HARPS on the bloated super-Neptune WASP-127b

J. V. Seidel, M. Lendl, V. Bourrier +17

WASP-127b is one of the puffiest exoplanets found to date, with a mass only Neptune masses, but a radius larger than Jupiter. It is also located at the border of the Neptune…

Revisiting Proxima with ESPRESSO

A. Suárez Mascareño, J. P. Faria, P. Figueira +88

We aim to confirm the presence of Proxima b using independent measurements obtained with the new ESPRESSO spectrograph, and refine the planetary parameters taking advantage of its…
