Variability type of MisV1147 Seiichi Yoshida Referring to: GCVS Variability Types and Distribution Statistics of Designated Variable Stars According to their Types of Variability http://www.sai.msu.su/groups/cluster/gcvs/gcvs/iii/vartype.txt a young stellar object can be classified one of the following types: I, IA, IB, IN, INA, INB, IS, ISA, ISB, INS, INSA, INSB, IT, INT, INST 1) Irregular variation First of all, "I" is attached because the variation is irregular. 2) Spectral class When the spectral class is between O-A, "A" is attached. When the spectral class is between F-M, "B" is attached. However, when the star is classified into 5) T Tauri type, "T" is attached instead of "B". 3) Nebulae When nebulae are found around the star, "N" is attached. 4) Rapid variation When the star shows about 0.5 or 1.0 mag variation in short time, within several hours or days, "S" is attached. 5) T Tauri type When the spectral class is between F-M, and the emission lines of Fe II at 4046/4132 angstrom and the absorption line of Li at 6707 angstrom are visible, "T" is attached. In the case of MisV1147, no nebula is found, so "N" is not attached. It shows the rapid variation, so "S" is attached. Therefore, the variability type of MisV1147 will be one of ISA, ISB or IST.
