Revisiting the formation of molecules and dust in core collapse supernovae
Isabelle Cherchneff, Dahbia Talbi, José Cernicharo
Context. Core-collapse Supernovae of Type II contribute the chemical enrichment of galaxies through explosion. Their role as dust producers in the high-redshift Universe may be of…
Atmospheric molecular blobs shape up circumstellar envelopes of AGB stars
L. Velilla-Prieto, J. P. Fonfría, M. Agúndez +8
During their thermally pulsing phase, Asymptotic Giant Branch (AGB) stars eject material that forms extended dusty envelopes. Visible polarimetric imaging found clumpy dust clouds…
SOFIA Far-infrared [O III] and [O I] Observations of Dense CO-knots in the Supernova Remnant Cassiopeia A: Multi-phase Ejecta
Jeonghee Rho, Sofia Wallstrom, Sebastien Muller +5
Dense, fast-moving ejecta knots in supernova remnants are prime sites for molecule and dust formation. We present SOFIA far-IR spectrometer FIFI-LS observations of CO-rich knots in…
An observational study of dust nucleation in Mira ( Ceti): II. Titanium oxides are negligible for nucleation at high temperatures
T. Kamiński, H. S. P. Müller, M. R. Schmidt +7
The formation of silicate dust in oxygen-rich envelopes of evolved stars is thought to be initiated by formation of seed particles that can withstand the high temperatures close to…
An observational study of dust nucleation in Mira ( Ceti): I. Variable features of AlO and other Al-bearing species
T. Kamiński, K. T. Wong, M. R. Schmidt +8
Context: Dust is efficiently produced by cool giant stars, but the condensation of inorganic dust is poorly understood. Aims: Identify and characterize aluminum bearing species in…
Molecules and dust in Cassiopeia A: II - Dust sputtering and diagnosis of dust survival in supernova remnants
Chiara Biscaro, Isabelle Cherchneff
We study the dust evolution in the supernova remnant Cassiopeia A. We follow the processing of dust grains that formed in the Type II-b supernova by modelling the sputtering of gra…
