Bottling the Champagne: Dynamics and Radiation Trapping of Wind-Driven Bubbles around Massive Stars

Sam Geen, Alex de Koter

In this paper we make predictions for the behaviour of wind bubbles around young massive stars using analytic theory. We do this in order to determine why there is a discrepancy be…

The Nearby Evolved Stars Survey II: Constructing a volume-limited sample and first results from the James Clerk Maxwell Telescope

P. Scicluna, F. Kemper, I. McDonald +89

The Nearby Evolved Stars Survey (NESS) is a volume-complete sample of 850 Galactic evolved stars within 3\,kpc at (sub-)mm wavelengths, observed in the CO (21) and…

The impact of the FMR and starburst galaxies on the (low-metallicity) cosmic star formation history

Martyna Chruslinska, Gijs Nelemans, Lumen Boco +1

The question how much star formation is occurring at low metallicity throughout the cosmic history appears crucial for the discussion of the origin of various energetic transients,…

Final Targeting Strategy for the SDSS-IV APOGEE-2S Survey

Felipe A. Santana, Rachael L. Beaton, Kevin R. Covey +43

APOGEE is a high-resolution (R sim 22,000), near-infrared, multi-epoch, spectroscopic survey of the Milky Way. The second generation of the APOGEE project, APOGEE-2, includes an ex…

Final Targeting Strategy for the SDSS-IV APOGEE-2N Survey

Rachael L. Beaton, Ryan J. Oelkers, Christian R. Hayes +57

APOGEE-2 is a dual-hemisphere, near-infrared (NIR), spectroscopic survey with the goal of producing a chemo-dynamical mapping of the Milky Way Galaxy. The targeting for APOGEE-2 is…

The Ionization Energies of Dust-Forming Metal Oxide Clusters

David Gobrecht, Jan Philip Sindel, Helena Lecoq-Molinos +1

Stellar dust grains are predominantly composed of mineralic, anorganic material forming in the circumstellar envelopes of oxygen-rich AGB stars. However, the initial stage of the d…

An MHD spectral theory approach to Jeans' magnetized gravitational instability

J. -B. Durrive, R. Keppens, M. Langer

In this paper, we revisit the governing equations for linear magnetohydrodynamic (MHD) waves and instabilities existing within a magnetized, plane-parallel, self-gravitating slab.…

The Galactic neutron star population I - an extragalactic view of the Milky Way and the implications for fast radio bursts

A. A. Chrimes, A. J. Levan, P. J. Groot +2

A key tool astronomers have to investigate the nature of extragalactic transients is their position on their host galaxies. Galactocentric offsets, enclosed fluxes and the fraction…

Mapping Luminous Hot Stars in the Galaxy

E. Zari, H. -W. Rix, N. Frankel +4

[Abridged] Luminous hot stars dominate the stellar energy input to the interstellar medium throughout cosmological time, they are laboratories to test theories of stellar evolution…

High angular resolution polarimetric imaging of the nucleus of NGC 1068: Disentangling the polarising mechanisms

L. Grosset, D. Rouan, F. Marin +8

Polarisation is a decisive method to study the inner region of active galactic nuclei (AGNs) since it is not affected by contrast issues similarly to how classical imaging is. When…

Gaia Early Data Release 3: The Galactic anticentre

Gaia Collaboration, T. Antoja, P. McMillan +417

We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of the Milky Way structure and evolution. We used astrometric positions, proper…
