Near-infrared monitoring of the accretion outburst in the massive young stellar object S255-NIRS3

Near-infrared monitoring of the accretion outburst in the massive young stellar object S255-NIRS3

We followed-up the massive young stellar object (MYSO) S255-NIRS3 (=S255-IRS1b) during its recent accretion outburst event in the Ks band with Kanata/HONIR for four years after its burst and obtained a long-term light curve. This is the most complete NIR light-curve of the S255-NIRS3 burst event that has ever been …
