cds-question@unistra.fryoung-stellar-objectsinfrared-photometryvisible-astronomybroad-band-photometryWe 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. These stars are as follows. (1) IRAS 02224+7227 (2MASS 02270555+7241167, HH 487S) exhibited FUor-like spectrum in our low-resolution optical spectra. The available photometric data restrict its luminosity to 23L_{sun}_<L_bol_<59L_{sun}_. (2) 2MASS 02263797+7304575, identified as a classical T Tauri star during our H{alpha} survey, exhibited an EXor-type brightening in 2005 November at the time of the Sloan Digital Sky Survey observations of the region. (3) 2MASSJ02325605+7246055, a low-mass embedded young star, associated with a fan-shaped infrared nebula, underwent an outburst between the DSS 1 and DSS 2 surveys, leading to the appearance of a faint optical nebula. Our [SII] and H{alpha} images, as well as the Spitzer Infrared Array Camera 4.5{mu}m images, revealed Herbig-Haro objects associated with this star. Our results suggest that amplitudes and timescales of outbursts do not necessarily correlate with the evolutionary stage of the stars.2014ApJ...795L..26Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/795/L26CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJS/224/22 : The YSO population of LDN 1340 in infrared (Kun+, 2016)J/MNRAS/458/3479 : SVM selection of WISE YSO Candidates (Marton+, 2016)J/ApJS/208/28 : H{alpha} survey in the ONC (Szegedi-Elek+, 2013)J/ApJS/208/9 : Intrinsic colors and temperatures of PMS stars (Pecaut+, 2013)J/A+A/551/A62 : V2492 Cyg light variations (Kospal+, 2013)J/MNRAS/413/2689 : PV Cep V(RI)c and IRAC photometry (Kun+, 2011)J/ApJ/733/L8 : Optical and IR photometry of [KOS94] HA11 (Kun+, 2011)J/A+A/507/881 : Emission lines in EX Lup optical spectrum (Sipos+, 2009)J/ApJ/704/606 : Protostars in the Vela Molecular Cloud (Giannini+, 2009)J/AJ/137/4377 : List of SEGUE plate pairs (Yanny+, 2009)J/ApJS/179/249 : Low-luminosity embedded protostar population (Dunham+, 2008)J/PASP/119/994 : MIPS 24um calibrators (Engelbracht+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/795/L26https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/795/L26http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/795/L26https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/795/L26https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/795/L26http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/795/L26GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJ/795/L26/table1Photometric data of the target starsJDUT date converted in JD by CDSdtime.epochcharrecnoRecord number assigned by the VizieR team.
