"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…

On the incidence of episodic accretion in Class I YSOs from VVV

Carlos Contreras Peña, Philip W. Lucas, Zhen Guo +1

Episodic accretion is one of the competing models to explain the observed luminosity spread in young stellar clusters. These short-lived high accretion events could also have a str…

The most variable VVV sources: eruptive protostars, dipping giants in the Nuclear Disc and others

P. W. Lucas, L. C. Smith, Z. Guo +16

We have performed a comprehensive search of a VISTA Variables in the Via Lactea (VVV) database of 9.5 yr light curves for variable sources with mag, aiming to provide…

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…

Spectroscopic confirmation of high-amplitude eruptive YSOs and dipping giants from the VVV survey

Zhen Guo, P. W. Lucas, R. Kurtev +17

During the pre-main-sequence (pre-MS) evolution stage of a star, significant amounts of stellar mass are accreted during episodic accretion events, such as multi-decade FUor-type o…

High energy gamma-ray sources in the VVV survey -- II. The AGN counterparts

Laura G. Donoso, Ana Pichel, Laura D. Baravalle +9

We identified Active Galactic Nuclei (AGN) candidates as counterparts to unidentified gamma-ray sources (UGS) from the Fermi-LAT Fourth Source Catalogue at lower Galactic latitudes…
