The Walkaway Star HP Tau/G2: Evidence for a Stellar Merger
Bo Reipurth, J. Bally, P. Friberg +6
HP~Tau/G2 is a luminous, short-period, fast-rotating G-type weak-line T Tauri star with a large radius, an oblate shape with gravity-darkening, little circumstellar material, and c…
iSHELL -band Survey of Class I and Flat Spectrum Sources: Magnetic field measurements in the protostellar phase
C. Flores, M. S. Connelley, B. Reipurth +2
We perform the first magnetic field strength survey of Class I and Flat Spectrum (FS) sources using -band observations with iSHELL. We obtained new observations of 42 Class I an…
Haro 5-2: A New Pre-Main Sequence Quadruple Stellar System
Bo Reipurth, C. Briceno, T. R. Geballe +9
We have discovered that the Halpha emission line star Haro 5-2, located in the 3-6 Myr old Ori OB1b association, is a young quadruple system. The system has a 2+2 configuration wit…
The 2022-2023 accretion outburst of the young star V1741 Sgr
Michael A. Kuhn, Lynne A. Hillenbrand, Michael S. Connelley +12
V1741 Sgr (= SPICY 71482/Gaia22dtk) is a Classical T Tauri star on the outskirts of the Lagoon Nebula. After at least a decade of stability, in mid-2022, the optical source brighte…
Modeling the Multiwavelength Evolution of the V960 Mon System
Adolfo S. Carvalho, Lynne A. Hillenbrand, Franz-Josef Hambsch +7
We study the evolution of the FU Ori object V960 Mon since its outburst, using available multi-wavelength photometric time series over 8 years, complemented by several epochs of mo…
The Effects of Starspots on Spectroscopic Mass Estimates of Low-mass Young Stars
C. Flores, M. S. Connelley, B. Reipurth +1
Magnetic fields and mass accretion processes create dark and bright spots on the surface of young stars. These spots manifest as surface thermal inhomogeneities, which alter the gl…
