NSV15573: confirmation of large-amplitude variation by Toa
Akira Takao (Kita-kyushu, Japan) reports the discovery of large-amplitude
variation in NSV15573.
NSV15573
= IRAS02433+6345 024321.0 +634542 (1950.0)
F12=20.89 F25=17.37 F60=2.29 F100=3.98L
VAR=99 LRS=29
blue, 10micron (silicate) emission, strength=9
IIIa: variable star with more evolved O-rich c.s. shell
= 024724.6 +635814 (2000.0) IRAS02433+6345 20.080 16.780 2.386 3.997L 99% 3(LRS)
= 024724.6 +635814 (2000.0) SSC02433+6345 20.080 16.780 2.386 3.997L
This observation supports that the star is a large-amplitude Mira star.
