HRMOS White Paper: Science Motivation
Laura Magrini, Thomas Bensby, Anna Brucalassi +52
The High-Resolution Multi-Object Spectrograph (HRMOS) is a facility instrument that we plan to propose for the Very Large Telescope (VLT) of the European Southern Observatory (ESO)…
Data downloaded via parachute from a NASA super-pressure balloon
Ellen L. Sirks, Richard Massey, Ajay S. Gill +40
In April to May 2023, the superBIT telescope was lifted to the Earth's stratosphere by a helium-filled super-pressure balloon, to acquire astronomical imaging from above (99.5% of)…
Nonlinear magnetic buoyancy instability and turbulent dynamo
Yasin Qazi, Anvar Shukurov, Devika Tharakkal +2
Stratified disks with strong horizontal magnetic fields are susceptible to magnetic buoyancy instability (MBI). Modifying the magnetic field and gas distributions, this can play an…
The HARPS search for southern extra-solar planets. XLVII. Five Jupiter-mass planets in long-period orbits, one highly irradiated Neptune, one brown dwarf, and five stellar binaries
Y. G. C. Frensch, G. Lo Curto, F. Bouchy +10
Our aim is to detect and characterise long-period companions around main sequence stars (spectral types late F to early M). We use the RV method to search for exoplanets around sta…
Small-scale dynamo with finite correlation times
Yann Carteret, Dominik Schleicher, Jennifer Schober
Fluctuation dynamos occur in most turbulent plasmas in astrophysics and are the prime candidates for amplifying and maintaining cosmic magnetic fields. A few analytical models exis…
Using [Ne V]/[Ne III] to Understand the Nature of Extreme-Ionization Galaxies
Nikko J. Cleri, Grace M. Olivier, Taylor A. Hutchison +14
Spectroscopic studies of extreme-ionization galaxies (EIGs) are critical to our understanding of exotic systems throughout cosmic time. These EIGs exhibit spectral features requiri…
