Bolometric Corrections for FU Ori Object Accretion Disk Luminosities
Adolfo S. Carvalho, Lynne A. Hillenbrand
The accretion luminosity of an FU Ori disk is a fundamental system parameter, but a challenging one to estimate for all but the most well-studied systems. FU Ori objects are dynami…
Robust support for semi-automated reductions of Keck/NIRSPEC data using PypeIt
Adolfo S. Carvalho, Greg Doppmann, Kyle B. Westfall +7
We present a data reduction pipeline (DRP) for Keck/NIRSPEC built as an addition to the PypeIt Python package. The DRP is capable of reducing multi-order echelle data taken both be…
The FUV Spectrum of FU Ori South
Adolfo S. Carvalho, Gregory J. Herczeg, Kevin France +1
The eruptive YSO FU Ori is the eponym of its variable class. FU Ori stars are known to undergo outbursts with amplitudes of magnitudes in the band and durations of several…
An FUV-detected Accretion Shock at the Star-Disk Boundary of FU Ori
Adolfo S. Carvalho, Lynne A. Hillenbrand, Kevin France +1
FU Ori objects are the most extreme eruptive young stars known. Their 4 to 5 magnitude photometric outbursts last for decades and are attributed to a factor of up to 10,000 increas…
A Dust-Trapping Ring in the Planet-Hosting Disk of Elias 2-24
Adolfo S. Carvalho, Laura M. Perez, Anibal Sierra +12
Rings and gaps are among the most widely observed forms of substructure in protoplanetary disks. A gap-ring pair may be formed when a planet carves a gap in the disk, which produce…
An Expanding Accretion Disk and a Warm Disk Wind As Seen In the Spectral Evolution of HBC 722
Adolfo S. Carvalho, Lynne A. Hillenbrand, Jerome Seebeck +1
We present a comprehensive analysis of the post-outburst evolution of the FU Ori object HBC 722 in optical/near-infrared (NIR) photometry and spectroscopy. Using a modified viscous…
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…
