    • ALMA observations of the nearby AGB star L2 Puppis II. Gas disk properties derived from 12CO and 13CO J = ... 
      Homan, Ward; Richards, Anita; Decin, Leen; Kervella, Pierre; Koter, Alex de; McDonald, Iain; Ohnaka, Keiichi (EDP Sciences, 2017-05)
      The circumstellar environment of the AGB star L-2 Puppis was observed with ALMA in cycle 3, with a resolution of 15 x 18 mas. The molecular emission shows a differentially rotating disk, inclined to a nearly edge-on position. ...
    • Study of the inner dust envelope and stellar photosphere of the AGB star R Doradus using SPHERE/ZIMPOL 
      Khouri, T.; Maercker, M.; Waters, L. B. F. M.; Vlemmings, Wouter H. T.; Kervella, Pierre; de Koter, A.; Ginski, C.; De Beck, E.; Decin, Leen; Min, M.; Dominik, Carsten; O'Gorman, E.; Schmid, H. M.; Lombaert, R.; Lagadec, E. (EDP Sciences, 2016)
      Context. On the asymptotic giant branch (AGB) low-and intermediate-mass stars eject a large fraction of their envelope, but the mechanism driving these outflows is still poorly understood. For oxygen-rich AGB stars, the ...
