Starspots as an Explanation for the Mysterious IYJ Continuum Excess Emission in Classical T Tauri Stars
Facundo Pérez Paolino, Jeff Bary, Lynne Hillenbrand +2
An accurate estimation of the continuum excess emission from accretion spots and inner circumstellar disk regions is crucial for a proper derivation of fundamental stellar paramete…
Observed Timescales of Stellar Feedback in Star-Forming, Low-Mass Galaxies
Laura C. Hunter, Liese van Zee, Roger E. Cohen +5
Understanding the timescales of atomic gas turbulence is crucial to understanding the interplay between star formation and the interstellar medium (ISM). To investigate the timesca…
Velocity-Resolved Reverberation Mapping of NGC 3227
Misty C. Bentz, Madison Markham, Sara Rosborough +4
We describe the results of a new reverberation mapping program focused on the nearby Seyfert galaxy NGC 3227. Photometric and spectroscopic monitoring were carried out from 2022 De…
Timescale of Stellar Feedback-Driven Turbulence in the ISM: A Deep Dive into UGC 4305
Laura Congreve Hunter, Liese van Zee, Kristen B. W. McQuinn +3
Understanding the interplay of stellar feedback and turbulence in the interstellar medium (ISM) is essential to modeling the evolution of galaxies. To determine the timescales over…
Cepheid-based Distances to NGC 4303 and NGC 1068
Madison Markham, Misty C. Bentz, Laura Ferrarese +2
We present Cepheid-based distances to two canonical AGN: NGC 4303 (M 61) and NGC 1068. Data were obtained using the Hubble Space Telescope with nonredundant time spacing over 12 vi…
The Effect of Starspots on Spectroscopic Age and Mass Estimates of Non-Accreting T~Tauri Stars in the Taurus-Auriga Star Forming Region
Facundo Pérez Paolino, Jeffrey S. Bary, Lynne A. Hillenbrand +1
Accurate age and mass determinations for young pre-main sequence stars are made challenging by the presence of large-scale starspots. We present results from a near-infrared spectr…
