Observational constraints on circumstellar dust [PDF]

There is an enormous range in the properties of stars that are losing mass. The red giants responsible for injecting roughly half or more of the material into the interstellar medium are reviewed. The physical properties are described for the out flowing

The Presolar Grain Database. I. Silicon Carbide

The Astrophysical Journal Supplement Series
The Presolar Grain Database (PGD) contains the vast majority of isotope data (published and unpublished) on presolar grains and was first released as a collection of spreadsheets in 2009.

Correlated Molybdenum, Ruthenium, and Barium Isotope Anomalies in Presolar Silicon Carbide Grains

The Astrophysical Journal
We have analyzed molybdenum, ruthenium, and barium isotopes simultaneously in 55 individual presolar silicon carbide (SiC) grains from the Murchison CM2 meteorite using the Chicago Instrument for Laser Ionization (or CHILI).

Discovery of a Variable Yellow Supergiant Progenitor for the Type IIb SN 2024abfo

The Astrophysical Journal Letters
We report the discovery of a progenitor candidate for the Type IIb SN 2024abfo using multiepoch pre-explosion images from the Hubble Space Telescope and the Dark Energy Camera Legacy Survey.

Intermediate-Mass Mergers: A New Scenario for Several FS CMa Stars

Galaxies
We summarise the properties and nature of a peculiar group of B-type stars called FS CMa stars. These stars show the B[e] phenomenon, i.e., their spectra exhibit both forbidden emission lines and infrared excess.
