Hyperion: The origin of the stars A far-UV space telescope for high-resolution spectroscopy over wide fields
Erika Hamden, David Schiminovich, Shouleh Nikzad +30
We present Hyperion, a mission concept recently proposed to the December 2021 NASA Medium Explorer announcement of opportunity. Hyperion explores the formation and destruction of m…
Theoretical and Observational Evidence for Coriolis Effects in Coronal Magnetic Fields Via Direct Current Driven Flaring Events
Darryl Z. Seligman, Leslie A. Rogers, Adina D. Feinstein +6
All stars produce explosive surface events such as flares and coronal mass ejections. These events are driven by the release of energy stored in coronal magnetic fields, generated…
Chronostar. II. Kinematic age and substructure of the Scorpius-Centaurus OB2 association
Maruša Žerjal, Michael J. Ireland, Timothy D. Crundall +2
The nearest region of massive star formation - the Scorpius-Centaurus OB2 association (Sco-Cen) - is a local laboratory ideally suited to the study of a wide range of astrophysical…
The Role of Outflows, Radiation Pressure, and Magnetic Fields in Massive Star Formation
Anna L. Rosen, Mark R. Krumholz
Stellar feedback in the form of radiation pressure and magnetically-driven collimated outflows may limit the maximum mass that a star can achieve and affect the star-formation effi…
Dynamics of small grains in transitional discs
Mark R. Krumholz, Michael J. Ireland, Kaitlin M. Kratter
Transitional discs have central regions characterised by significant depletion of both dust and gas compared to younger, optically-thick discs. However, gas and dust are not deplet…
Helium and Nitrogen Enrichment in Massive Main Sequence Stars: Mechanisms and Implications for the Origin of WNL Stars
Arpita Roy, Ralph S Sutherland, Mark R Krumholz +2
The evolutionary paths taken by massive stars with remain substantially uncertain. They begin their lives as main sequence (MS) O-stars. Dependin…
