The FU Ori outburst of PR Ori B

Carlos Contreras Pena, Zsofia Nagy, Gregory Herczeg +42

We report the discovery of a nearby FU Ori-type outburst (FUor), PR Ori B, in the L1641 cluster of the Orion star-forming region. The high-amplitude variability was first identifie…

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…

The long-term outburst(s) of GPSV16: from an intermediate to a FUor classification

Carlos Contreras Peña, Jeong-Eun Lee, Philip W. Lucas +8

FU Ori outbursts are thought to play a key role in stellar mass assembly and in the chemistry of protoplanetary disks during the early formation of stars. However, uncertainties re…

Characterizing the Low-Mass Pre-Main-Sequence Population in the Low-Metallicity Star-Forming Region Dolidze 25 Using VLT-MUSE

Mizna Ashraf, Jessy Jose, Gregory J. Herczeg +6

The metallicity of the star-forming environment is a fundamental parameter shaping the evolution of protoplanetary disks and the formation of planetary systems, yet its influence r…

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…

"Oh FUors where art thou": A search for long-lasting YSO outbursts hiding in infrared surveys

Carlos Contreras Peña, Jeong-Eun Lee, Ho-Gyu Lee +11

Long-lasting episodes of high accretion can strongly impact stellar and planetary formation. However, the universality of these events during the formation of young stellar objects…

Search for Brown Dwarfs in IC 1396 with Subaru HSC: Interpreting the Impact of Environmental Factors on Sub-stellar Population

Saumya Gupta, Jessy Jose, Swagat Ranjan Das +4

Young stellar clusters are predominantly the hub of star formation and hence, ideal to perform comprehensive studies over the least explored sub-stellar regime. Various unanswered…

Multi-wavelength detection of an ongoing FUOr-type outburst on a low-mass YSO

Zhen Guo, P. W. Lucas, R. G. Kurtev +13

During the pre-main-sequence evolution, Young Stellar Objects (YSOs) assemble most of their mass during the episodic accretion process. The rarely seen FUOr-type events (FUOrs) are…

An outburst and FU Ori-type disk of a former low luminosity protostar

Mizna Ashraf, Jessy Jose, Ho-Gyu Lee +5

Strong accretion outbursts onto protostars are associated with emission dominated by a viscously heated disk, which is characterized by high luminosities. We report the discovery a…

New Eruptive YSOs from SPICY and WISE

C. Contreras Peña, M. Ashraf, J. E. Lee +6

This work presents four high-amplitude variable YSOs ( 3 mag at near- or mid-IR wavelengths) arising from the SPICY catalog. Three outbursts show a duration that is longer…

Twenty-Five Years of Accretion onto the Classical T Tauri Star TW Hya

Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati +39

Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time…
