Also shorter periods. MACHO data resolves the symbiotic from the surrounding stars in a very crowded area. There are at least 4 stars (mag. 16-17) inside a 8" radius and several more less than 25" apart. The variable itself is in a close pair with the brighter star UCAC4 319-167999 (V= 14.5; 2" away at 18 20 19.20 -26 22 47.8). The magnitudes published in the literature are for the blend. |
