    • ALMA observations of the nearby AGB star L-2 Puppis I. Mass of the central star and detection of a candidate planet 
      Kervella, Pierre; Richards, A. M. S.; Decin, L.; McDonald, I.; Montargès, M.; Ohnaka, K. (EDP Sciences, 2016)
      Six billion years from now, while evolving on the asymptotic giant branch (AGB), the Sun will metamorphose from a red giant into a beautiful planetary nebula. This spectacular evolution will impact the solar system planets, ...
    • An updated 2017 astrometric solution for betelgeuse 
      Harper, G. M.; Brown, A.; Guinan, E. F.; O’Gorman, E.; Richards, A. M. S.; Kervella, P.; Decin, L. (IOP Publishing, 2017)
      We provide an update for the astrometric solution for the Type II supernova progenitor Betelgeuse using the revised Hipparcos Intermediate Astrometric Data (HIAD) of van Leeuwen, combined with existing VLA and new e-MERLIN ...
    • The inhomogeneous submillimeter atmosphere of Betelgeuse 
      O'Gorman, E.; Kervella, P.; Harper, G. M.; Richards, A. M. S.; Decin, L.; Montarges, M.; McDonald, I. (EDP Sciences, 2017)
      The mechanisms responsible for heating the extended atmospheres of early-M spectral-type supergiants are poorly understood. So too is the subsequent role these mechanisms play in driving the large mass-loss rates of these ...
