Gaia Data Release 3. Summary of the variability processing and analysis
L. Eyer, M. Audard, B. Holl +55
Context. Gaia has been in operations since 2014. The third Gaia data release expands from the early data release (EDR3) in 2020 by providing 34 months of multi-epoch observations t…
Dipper-like variability of the Gaia alerted young star V555 Ori
Zsófia Nagy, Elza Szegedi-Elek, Péter Ábrahám +26
V555 Ori is a T Tauri star, whose 1.5 mag brightening was published as a Gaia science alert in 2017. We carried out optical and near-infrared photometric, and optical spectroscopic…
Gaia 18dvy: a new FUor in the Cygnus OB3 association
E. Szegedi-Elek, P. Ábrahám, L. Wyrzykowski +59
We present optical-infrared photometric and spectroscopic observations of Gaia18dvy, located in the Cygnus OB3 association at a distance of 1.88 kpc. The object was noted by the Ga…
Identification of Young Stellar Object candidates in the DR2 x AllWISE catalogue with machine learning methods
G. Marton, P. Ábrahám, E. Szegedi-Elek +8
The second Data Release (DR2) contains astrometric and photometric data for more than 1.6 billion objects with mean magnitude 20.7, including many Young Stella…
The young star population of L1188
Elza Szegedi-Elek, Mária Kun, Attila Moór +2
We present new results on the young star population of the Lynds~1188 molecular cloud, associated with the Cepheus Bubble, a giant interstellar shell around the association Cep~OB\…
Gaia Data Release 2: Summary of the variability processing & analysis results
B. Holl, M. Audard, K. Nienartowicz +60
The Gaia Data Release 2 (DR2): we summarise the processing and results of the identification of variable source candidates of RR Lyrae stars, Cepheids, long period variables (LPVs)…
An UXor among FUors: extinction related brightness variations of the young eruptive star V582 Aur
P. Ábrahám, Á. Kóspál, M. Kun +24
V582 Aur is an FU Ori-type young eruptive star in outburst since 1985. The eruption is currently in a relatively constant plateau phase, with photometric and spectroscopic va…
The star formation environment of the FU Ori type star V582 Aur
Maria Kun, Elza Szegedi-Elek, Bo Reipurth
We have studied the environment of the FU Ori type star V582 Aur. Our aim is to explore the star-forming region associated with this young eruptive star. Using slitless spectroscop…
Multi-wavelength study of the low-luminosity outbursting young star HBC 722
Á. Kóspál, P. Ábrahám, J. A. Acosta-Pulido +22
HBC 722 (V2493 Cyg) is a young eruptive star in outburst since 2010. It is an FU Orionis-type object with an atypically low outburst luminosity. Because it was well characterized i…
The intermediate-mass star-forming region Lynds 1340. An optical view
M. Kun, A. Moór, E. Szegedi-Elek +1
We have performed an optical spectroscopic and photometric search for young stellar objects associated with the molecular cloud Lynds 1340, and examined the structure of the cloud…
Extensive Spectroscopy and Photometry of the Type IIP Supernova 2013ej
G. Dhungana, R. Kehoe, J. Vinko +32
We present extensive optical (, , and open CCD) and near-infrared () photometry for the very nearby Type IIP SN ~2013ej extending from +1 to +461 days after…

M. Kun, D. Apai, J. O'Linger-Luscusk +4
We report on the discovery of three candidate eruptive young stars, found during our comprehensive multi-wavelength study of the young stellar population of the dark cloud L1340. T…
A New Halpha Emission-Line Survey in the Orion Nebula Cluster
Elza Szegedi-Elek, Mária Kun, Bo Reipurth András Pal +2
We present results from an Halpha emission-line survey in a one square degree area centered on the Orion Nebula Cluster, obtained with the Wide Field Grism Spectrograph-2 on the 2.…
Exploring the circumstellar environment of the young eruptive star V2492 Cyg
Á. Kóspál, P. Ábrahám, J. A. Acosta-Pulido +20
Context. V2492 Cyg is a young eruptive star that went into outburst in 2010. The near-infrared color changes observed since the outburst peak suggest that the source belongs to a n…
