J. M. Winters, D. T. Hoai, K. T. Wong +6
The latest evolutionary phases of low- and intermediate mass stars are characterized by complex physical processes like turbulence, convection, stellar pulsations, magnetic fields,…
Morpho-kinematics of the wind of AGB star L Pup
D. T. Hoai, P. T. Nhung, P. Darriulat +4
Single dish observations of AGB star L Pup have revealed exceptionally low mass loss rate and expansion velocity, challenging interpretations in terms of standard wind models.…
