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…
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…
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…
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…
