A New FU Orionis Accretion Outburst in the W5 HII Region
Lynne A. Hillenbrand, Matthew J. Graham, Mansi M. Kasliwal +9
We announce a recently detected outburst that is currently only a few months old, and probably of FU Orionis type. The progenitor to the outburst was an emission-line, flat-spectru…
Hubble reveals complex multi-scale structure in the edge-on protoplanetary disk IRAS 23077+6707
Kristina Monsch, Joshua B. Lovell, Karl R. Stapelfeldt +11
We present high-resolution () Hubble Space Telescope (HST)/Wide Field Camera 3 (WFC3) imaging of the near edge-on () protoplanetary disk IRAS 23077…
The Near-Ultraviolet Spectra of FU Orionis Accretion Disks
Adolfo S. Carvalho, Lynne A. Hillenbrand, Gregory J. Herczeg +1
We present the results of the first high-sensitivity NUV (1800 to 3200 Å) survey of FU Ori objects, using the \textit{Hubble Space Telescope} (HST) STIS spectrograph. We compare ne…
The Outbursting YSOs Catalogue (OYCAT)
C. Contreras Peña, J. -E. Lee, G. Herczeg +39
YSOs can display unpredictable and high-amplitude rises in brightness that can last from a few months to possibly over 100 years. These types of outbursts are explained by large ch…
The Hot Inner AU of V883 Ori
Adolfo S. Carvalho, Lynne A. Hillenbrand, Ágnes Kóspál
The V883 Ori system is a rapidly accreting young stellar object that has been used as a laboratory for studying the molecular inventory of young circumstellar disks with high lumin…
FUOr-Aur 0544+3330: A New YSO Outburst in the Outskirts of Auriga OB1, Viewed Face-On
Lynne A. Hillenbrand, Adolfo S. Carvalho, Dan Stern +5
We present a newly appreciated FU Ori outburst event that began in 2019 and reached a peak in early 2021. Suspected young stellar object WISE J054452.25+333009.6 experienced substa…
Spectral Biases, Starspot Morphology, and Dynamo Transitions on the Pre-Main Sequence: Insights from the X-Shooter WTTS Library
Facundo Pérez Paolino, Jeff Bary, Benjamin Horner +2
Starspots are ubiquitous in young, low-mass stars, yet their impact on the spectral classification and fundamental parameter inference of pre-main sequence stars (PMS) has been lar…
Rosette Nebula Outburst Gaia 24djk from the Young Stellar Object V557 Mon
Adolfo S. Carvalho, Lynne A. Hillenbrand
A previously faint young stellar object (YSO), V557 Mon, rapidly brightened in late 2024 and is currently at least magnitudes brighter than its typical pre-outburst bright…
