A catalogue of high angular resolution and contrast polarimetric maps of 45 nearby AGB stars with SPHERE/ZIMPOL
Nekolgne Aymard Badolo, Eric Lagadec, Mamadou N'Diaye +7
We present the largest catalogue of asymptotic giant branch (AGB) stars, 45 targets in total, observed in polarized light at high angular resolution (~ 20 milliarcsec). The main go…
Atomium: The astounding complexity of the near circumstellar environment of the M-type AGB star R Hydrae. I. Morpho-kinematical interpretation of CO and SiO emission
Ward Homan, Bannawit Pimpanuwat, Fabrice Herpin +36
Evolved low- to intermediate-mass stars are known to shed their gaseous envelope into a large, dusty, molecule-rich circumstellar nebula which typically develops a high degree of s…
Atomium: A high-resolution view on the highly asymmetric wind of the AGB star Pi1 Gruis. I. First detection of a new companion and its effect on the inner wind
Ward Homan, Miguel Montarges, Bannawit Pimpanuwat +35
The nebular circumstellar environments of cool evolved stars are known to harbour a rich morphological complexity of gaseous structures on different length scales. A large part of…
Optimizing exoplanet atmosphere retrieval using unsupervised machine-learning classification
Joshua J. C. Hayes, E. Kerins, S. Awiphan +6
One of the principal bottlenecks to atmosphere characterisation in the era of all-sky surveys is the availability of fast, autonomous and robust atmospheric retrieval methods. We p…
An Infrared Census Of Dust In Nearby Galaxies With Spitzer (DUSTiNGS): V. The Period-luminosity Relation For Dusty Metal-Poor AGB Stars
Steven R. Goldman, Martha L. Boyer, Kristen B. McQuinn +10
The survey for DUST In Nearby Galaxies with Spitzer (DUSTiNGS) has identified hundreds of candidate dust-producing Asymptotic Giant Branch (AGB) stars in several nearby metal-poor…
EU Del: exploring the onset of pulsation-driven winds in giant stars
I. McDonald, A. A. Zijlstra, G. C. Sloan +5
We explore the wind-driving mechanism of giant stars through the nearby (117 pc), intermediate-luminosity ( L) star EU Del (HIP 101810, HD 196610). APEX obs…
Photometric properties of carbon stars in the Small Magellanic Cloud
G. C. Sloan, E. Lagadec, K. E. Kraemer +4
The Optical Gravitational Lensing Experiment identified over 1,800 carbon-rich Mira and semi-regular variables in the Small Magellanic Cloud. Multi-epoch infrared photometry reveal…
VISTA variables in the Sagittarius dwarf spheroidal galaxy: pulsation- vs. dust-driven winds on the giant branches
Iain McDonald, Albert A. Zijlstra, Gregory C. Sloan +3
Variability is examined in over 2.6 million stars covering 11 square degrees of the core of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) from VISTA Z-band observations. Gener…
Dust production and mass loss in the Galactic globular cluster 47 Tucanae
Iain McDonald, Martha L. Boyer, Jacco Th. van Loon +1
Dust production among post-main-sequence stars is investigated in the Galactic globular cluster 47 Tucanae (NGC 104) based on infrared photometry and spectroscopy. We identify meta…
