Hot water emission during an outburst in a classical T Tauri star
Zhen Guo, Javier Osses, Vitor Fermiano +34
In this paper, we present observations of an eruptive young star in the Rosette Nebula, identified by the Gaia Science Alerts system using Gaia time series data. We aim to investig…
A Parameterized YSO Accretion Disk Model with Increasing Accretion Rate: Predicted Outburst Lightcurves
Gautam Das, Lynne A. Hillenbrand, Adolfo S. Carvalho
A sub-class among Young Stellar Objects (YSOs), known as FU Ori type stars, undergo sudden rises in luminosity by several orders of magnitude on timescales of a few months to a few…
Quantitative Spectroscopic Diagnostics for FU Orionis-Type Young Stellar Objects
Evan R. Portnoi, Lynne A. Hillenbrand, Adolfo S. Carvalho
We present near-infrared spectroscopic diagnostics that can be used to identify FU Orionis stars (FUOrs). FUOrs are young stellar objects (YSOs) that are currently in a state of ex…
The FUor Mass Distribution Matches the Solar Neighborhood IMF: Evidence for a Universal Eruptive Phase
Adolfo S. Carvalho, Lynne A. Hillenbrand
Eruptive accretion events are expected to play an important role in the mass buildup stage of individual star formation. FU Ori objects (FUors) experience the most extreme eruptive…
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…
