M 1-92: The Death of an AGB Star Told by Its Isotopic Ratios

Sánchez Contreras, Carmen; Masa, Elisa; Alcolea, Javier +3 more

Ongoing improvements in the sensitivity of sub-mm- and mm-range interferometers and single-dish radio telescopes allow for the increasingly detailed study of AGB and post-AGB objects in molecular species other than CO12

Correlations between IR Luminosity, Star Formation Rate, and CO Luminosity in the Local Universe

De Zotti, Gianfranco; Bianchi, Simone; Casasola, Viviana +5 more

We exploit the DustPedia sample of galaxies within approximately 40 Mpc, selecting 388 sources, to investigate the correlations between IR luminosity (L_IR), the star formation rate (SFR), and the CO(1-0) luminosity (L_CO) down to much lower luminosities than reached by previous analyses. We find a sub-linear dependence of the …

The Interstellar Medium of Dwarf Galaxies

Hunt, Leslie K.; Izotov, Yuri I.; Henkel, Christian

Dwarf galaxies are by far the most numerous galaxies in the Universe, showing properties that are quite different from those of their larger and more luminous cousins. This review focuses on the physical and chemical properties of the interstellar medium of those dwarfs that are known to host significant amounts of gas and dust. The neutral and io…

Spectroscopy of Planetary Nebulae with Herschel: A Beginners Guide

Exter, Katrina

A brief overview of the Herschel Space Telescope PACS and SPIRE spectrographs is given, pointing out aspects of working with the data products that should be considered by anyone using them. Some preliminary results of Planetary Nebulae (PNe) taken from the Herschel Planetary Nebula Survey (HerPlaNs) programme are then used to demonstrate what can…
