Asymptotic giant branch stars in the Large Magellanic Cloud: evolution of dust in circumstellar envelopes [PDF]
, 2015 We calculated theoretical evolutionary sequences of asymptotic giant branch (AGB) stars, including formation and evolution of dust grains in their circumstellar envelope.

Insights Into the Gas-Phase Structure and Internal Dynamics of Diphenylsilane: A Broadband Rotational Spectroscopy Study. [PDF]
ChemphyschemThe structure of diphenylsilane could be determined from the rotational spectra of all its singly substituted heavy atom isotopologues. A comparison with its oxygen analogue diphenylether revealed some interesting differences in the internal dynamics as well as in the gas‐phase structure.

Atacama Large Aperture Submillimeter Telescope (AtLAST) science: Our Galaxy [version 2; peer review: 2 approved] [PDF]
Open Research EuropeAs we learn more about the multi-scale interstellar medium (ISM) of our Galaxy, we develop a greater understanding for the complex relationships between the large-scale diffuse gas and dust in Giant Molecular Clouds (GMCs), how it moves, how it is ...

Meridional Circulation of Dust and Gas in the Circumstellar Disk: Delivery of Solids onto the Circumplanetary Region [PDF]
Astrophysical Journal, 2021 We carried out 3D dust + gas radiative hydrodynamic simulations of forming planets. We investigated a parameter grid of a Neptune-mass, a Saturn-mass, a Jupiter-mass, and a five-Jupiter-mass planet at 5.2, 30, and 50 au distance from their star. We found

NIKA2 observations around LBV stars Emission from stars and circumstellar material [PDF]
EPJ Web of Conferences, 2020 Luminous Blue Variable (LBV) stars are evolved massive objects, previous to core-collapse supernova. LBVs are characterized by photometric and spectroscopic variability, produced by strong and dense winds, mass-loss events and very intense UV radiation ...

Yellow Supergiants and Post-red Supergiant Evolution in the Large Magellanic Cloud
The Astronomical Journal, 2023 The empirical evidence for an upper-mass limit for the red supergiant (RSG) progenitors of the Type II-P SNe at about 18 MSun, raises questions about the fate of the most luminous, most massive RSGs.

Dust Disks Around Young Stellar Objects [PDF]
Journal of Astronomy and Space Sciences, 2016 To reproduce the spectral energy distributions (SEDs) of young stellar objects (YSOs), we perform radiative transfer model calculations for the circumstellar dust disks with various shapes and many dust species.

AGB Stars and Their Circumstellar Envelopes. I. the VULCAN Code
Universe, 2021 The interplay between AGB interiors and their outermost layers, where molecules and dust form, is a problem of high complexity. As a consequence, physical processes like mass loss, which depend on the chemistry of the circumstellar envelope, are often ...

Supernova 2014C: Ongoing Interaction with Extended Circumstellar Material with Silicate Dust [PDF]
Astrophysical Journal, 2019 Supernova (SN) 2014C is unique: a seemingly typical hydrogen-poor SN that started to interact with a dense, hydrogen-rich circumstellar medium (CSM) ∼100 days post-explosion.
