SPICY 30021: an embedded bona fide FUor with a mid-infrared precursor
Zhen Guo, Calum Morris, Vitor Fermiano +37
Unstable mass accretion in young stellar objects (YSOs) often leads to observable outbursts, which play a key role in stellar mass assembly during pre-main-sequence evolution. The…
Conspicuous Gas, Cryptic Dust: Spectroscopy and Chromaticity of Complex Periodic Variables
Luke G. Bouma, Facundo Perez Paolino, Lynne A. Hillenbrand +17
Complex periodic variables (CPVs) are young low-mass stars whose light curves show periodic dips indicative of transiting corotating material. The origin and composition of this ma…
VLASS Discovery of a Luminous Galactic Radio Transient Evolving on Decade Timescales
Jessie M. Miller, Gregg Hallinan, Dillon Dong +10
We present a multiwavelength analysis of the radio transient VT J1906+0849, discovered as a 70 mJy source in Epoch 1 of the Very Large Array Sky Survey (VLASS), 21 yr after an NRAO…
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…
