The Post-Outburst Spectrum of L1415-IRS
Lynne A. Hillenbrand, Thomas P. Greene, Evan R. Portnoi +1
We present near-infrared spectroscopic observations of L1415-IRS, a Class I type young stellar object that underwent a factor of 30 photometric outburst in the early 2000s. Ours…
Rotational Modulation and Long-Term Variability of Magnetic Fields in T-Tauri Stars with IGRINS
Facundo Pérez Paolino, Lynne Hillenbrand, Jeff Bary
Magnetic fields play a central role in the evolution of pre-main-sequence (PMS) stars, yet direct observational constraints on their variability over rotational and multi-year time…
Older Ages for 23 Pre-Main Sequence Stars in Upper Scorpius Using Dynamical Mass-Constrained Stellar Evolutionary Models
Allison P. M. Towner, Joshua A. Eisner, Patrick D. Sheehan +2
We present revised stellar ages for 23 pre-main sequence K- and M-type stars in the Upper Scorpius star-forming region, derived by using stellar dynamical masses to constrain isoch…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
