The bright southern star L2 Pup is a particularly prominent asymptotic giant branch (AGB) star, located at a distance of only 64 pc. We report new adaptive optics observations of L2 Pup at visible wavelengths with the SPHERE/ZIMPOL instrument of the VLT that confirm the presence of the circumstellar dust disk discovered recently. This disk is seen almost almost edge-on at an inclination of 82 . The signature of its three-dimensional structure is clearly observed in the map of the degree of… Expand
ALMA observations of the nearby AGB star L2 Puppis - I. Mass of the central star and detection of a candidate planet
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 impactExpand
ALMA observations of the nearby AGB star L2 Puppis - II. Gas disk properties derived from 12CO and 13CO J = 3–2 emission
The circumstellar environment of the AGB star L2 Puppis was observed with ALMA in cycle 3, with a resolution of 15 × 18 mas. The molecular emission shows a differentially rotating disk, inclined to aExpand
Infrared interferometric imaging of the compact dust disk around the AGB star HR3126 with the bipolar Toby Jug Nebula
The asymptotic giant branch (AGB) star HR3126, associated with the arcminute-scale bipolar Toby Jug Nebula, provides a rare opportunity to study the emergence of bipolar structures at the end of theExpand
The nearby AGB star L2 Puppis: the birth of a planetary nebula ?
Adaptive optics observations in the infrared (VLT/NACO, Kervella et al. 2014) and visible (VLT/SPHERE, Kervella et al. 2015) domains revealed that the nearby AGB star L2 Pup (d=64 pc) is surroundedExpand
The protoplanetary system HD 100546 in H α polarized light from SPHERE/ZIMPOL: A bar-like structure across the disk gap?
Context. HD 100546 is one of the few known pre-main-sequence stars that may host a planetary system in its disk. Aims. This work aims to contribute to our understanding of HD 100546 by analyzing newExpand
The inner circumstellar dust of the red supergiant Antares as seen with VLT/SPHERE/ZIMPOL
The processes by which red supergiants lose mass are not fully understood thus-far and their mass-loss rates lack theoretical constraints. The ambient surroundings of the nearby M0.5 Iab star AntaresExpand
Resolved imaging of the AR Puppis circumbinary disk
Circumbinary disks are common around post-asymptotic giant branch (post-AGB) stars with a stellar companion on orbital time scales of a few 100 to few 1000 days. The presence of a disk is usuallyExpand
ALMA detection of a tentative nearly edge-on rotating disk around the nearby AGB star R~Doradus
A spectral scan of the circumstellar environment of the asymptotic giant branch (AGB) star R~Doradus was taken with ALMA in cycle 2 at frequencies between 335 and 362 GHz and with a spatialExpand
Ultraviolet emission from main-sequence companions of AGB stars
Although the majority of known binary Asymptotic Giant Branch (AGB) stars are symbiotic systems (i.e. with a WD as a secondary star), main-sequence companions of AGB stars can be more numerous, evenExpand
Interferometric observations of SiO thermal emission in the inner wind of M-type AGB stars IK Tauri and IRC+10011.
There is a strong coupling between the depletion of gas-phase SiO and gas acceleration in the inner envelope of M-type AGB stars, which could be explained by the condensation of SiO into dust grains. Expand
