RW Tri - its Negative Superhumps and System Parameters

Abstract

Negative superhumps are detected in the light curves of RW Tri collected in September 1994 (Smak 1995) and November/December 1957 (Walker 1963). New system parameters, obtained using $K_{2}$ and $V_{2, r o t} sin i$ (from Poole et al. 2003) and $q$ (estimated from $P_{n S H}$ ), are $M_{1} = 0.60 \pm 0.20 M ⊙$ , $M_{2} = 0.48 \pm 0.15 M ⊙$ , $A = 1.13 \pm 0.09 \times 1 0^{11}$ cm and $i = 72.5 \pm 2.5$ .
