Organic Synthesis in the Late Stages of Stellar Evolution [PDF]
EAS Publications Series, 2015 Infrared and mm-wave observations have revealed a rapid and continuous synthesis of gas-phase and solid organic compounds in the late stages of stellar evolution. This process gives rise to an amorphous carbonaceous compound of mixed aromatic and aliphatic structure which is probably responsible for the unidentified infrared emission (UIE) bands that ...

AGB Winds with Gas-Dust Drift in Stellar Evolution Codes
Universe, 2021 A significant fraction of new metals produced in stars enter the interstellar medium in the form of dust grains. Including dust and wind formation in stellar evolution models of late-stage low- and intermediate-mass stars provides a way to quantify their

Jsolated Stars of Low Metallicity
Galaxies, 2018 We study the effects of a reduced mass-loss rate on the evolution of low metallicity Jsolated stars, following our earlier classification for angular momentum (J) isolated stars.

Simulations and Modeling of Intermediate Luminosity Optical Transients and Supernova Impostors
Galaxies, 2018 More luminous than classical novae, but less luminous than supernovae, lies the exotic stellar eruptions known as Intermediate luminosity optical transients (ILOTs).

Fictions, Conditionals, and Stellar Astrophysics [PDF]
, 2013 This article argues in favour of an inferential role for fictions in scientific modelling. The argument proceeds by means of a detailed case study, namely models of the internal structure of stars in stellar astrophysics.

Late Stages of Stellar Evolution [PDF]
Symposium - International Astronomical Union, 1995 A review is given of the use of high-accuracy astrometry on research on white dwarfs and the hot subdwarfs and central stars of planetary nebulae (CSPN). Predictions are made about the expected impact of HIPPARCOS, and the possible impacts of GAIA and ROEMER.

Late stages of stellar evolution
New Astronomy Reviews, 2004 The Square Kilometer Array will have the sensitivity, spatial resolution, and frequency resolution to provide new scientific knowledge of evolved stars. Four basic areas of scientific exploration are enhanced by the construction of the SKA: 1) detection and imaging of photospheric radio continuum emission and position correlation with maser ...

Asteroseismic Observations of Hot Subdwarfs
Frontiers in Astronomy and Space Sciences, 2021 There are a number of reasons for studying hot subdwarf pulsation; the most obvious being that these stars remain a poorly understood late-stage of stellar evolution and knowledge of their interior structure, which pulsation studies reveal, constrains ...
