||JOIN OUR TEAM
||We are recruiting a new team member with a background in Optical Engineering to work in the Exeter Exoplanet Lab on the integration of the
BIFROST instrument. For further information, see the posting on the AAS Job Register and Exeter Job Application Portal (post P87138).
|1-3 March 2023
||The Exeter BIFROST team travels to Leuven to attend the
"Asgard Workshop", where we discuss the progress on BIFROST with colleagues from the Asgard team and ESO representatives.
||EAS session on GAIA binaries
||We are organising a lunch session on the
GAIA-BIFROST Legacy Survey (LS8).
The session is scheduled for July 10th at the EAS conference in Krakow, Poland. Abstracts for posters are accepted until March 8th.
