Mid-Infrared and Maser Flux Variability Correlation in Massive Young Stellar Object G036.70+00.09

Mizuho Uchiyama, Kohei Ichikawa, Koichiro Sugiyama +2

We present the discovery of the simultaneous flux variation of a massive young stellar object (MYSO) G036.70+00.09 (G036.70) both in the maser emission and mid-infrared (MIR;-…

Near-infrared Monitoring of the Accretion Outburst in the MYSO S255-NIRS3

Mizuho Uchiyama, Takuya Yamashita, Koichiro Sugiyama +10

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…

WISE Discovery of Mid-infrared Variability in Massive Young Stellar Objects

Mizuho Uchiyama, Kohei Ichikawa

We systematically investigate the mid-infrared (MIR; m) time variability of uniformly selected massive young stellar objects (MYSOs) from the Red MSX Source (RMS)…

The shortest periodic and flaring flux variability of a methanol maser emission at 6.7 GHz in G 014.23-00.50

Koichiro Sugiyama, Katsura Nagase, Yoshinori Yonekura +9

We detected flaring flux variability that regularly occurred with the period of 23.9 days on a 6.7 GHz methanol maser emission at Vlsr = 25.30 km/s in G 014.23-00.50 through highly…
