VSP Note: 16.5 mag. red companion (variable?) 20" to the South. |

J-K= 2.58:; B-V= 4.2 (SDSS). Magnitudes from Dahlmark corrected using formula in IBVS 3855 and B-V~4. The finding chart in IBVS 3855 points to the Southern component of a 20" binary but both the Dauban and the Misao survey detect the Northern component as strongly variable. Combination of data from NSVS, Misao and Dahlmark reveals that they are one and the same mira so Dahlmark's identification is wrong. The other star is 2MASS J20094414+3158496 (J= 7.90; J-K= 1.95) and has V= 16.5 (UCAC4), V= 16.5 (CMC14) and V= 16.4; B-V= 3.2 (SDSS). Because of its colors, period and bump in the ascending branch, this is probably a carbon mira. |
