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…
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…
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…
H emission line sources from VLT-MUSE in a low-metallicity star forming region -- Dolidze 25
Mizna Ashraf, Jessy Jose, Gregory Herczeg +1
The process of accretion through circumstellar disks in young stellar objects is an integral part of star formation and the emission line is a prominent signature of accretion…
Photometric and Spectroscopic monitoring of YSOs in nearby star forming regions. I. Eruptive YSOs
Carlos Contreras Peña, Gregory J. Herczeg, Mizna Ashraf +7
Mid-infrared (mid-IR) variability in young stellar objects (YSOs) is driven by several physical mechanisms, which produce a variety of amplitudes and light curve shapes. One of the…
