Table 1: Observed and calculated physical and dynamical characteristics of the ellipsoidal stellar wind bubble surrounding 3C 434.1.
Table 2: Comparison of observed SWB parameters to those calculated from a simple time-evolution model of a SWB formed by the wind of a single O5.5V star, chosen to match the observed wind luminosity $L_{\rm w}$ at the minimum age of the bubble (t=1.4 Myr). Model is from McKee et al. (1984). The stall velocity and age for the bubble are near the lower and upper limits of those same parameters as measured, respectively. The stall radius is 30% larger than the observed radius, but is within uncertainties. The SWB surrounding 3C 434.1 is apparently in its early stages of dissipation.
Table 3: Eleven stars towards 3C 434.1 with observed reddenings that are consistent with that observed toward the SNR/SWB ( E(B-V)=2.1 mag), i.e. $1.7~{\rm mag} \leq E(B-V) \leq 2.5$ mag. The uncertainty in the assigned spectral type is on average plus or minus one sub-type (e.g. an O5 is O4-O6 within uncertainty). Distances are calculated using reddening law R_V=A_V/E(B-V)=3.1. All distances have an uncertainty of $\pm$ 30%.
Table 4: Four stars from Table 3 with photometric distances and reddenings consistent with the SWB around 3C 434.1. Sources of the physical values $v_{\infty }$ , luminosity, mass and effective temperature are from Schaerer & de Koter (1997).
