... emission is probably the result of the superposition of (at least) three main contributions: i) the heavily extincted stellar photosphere of a massive young stellar object (the ultimate energy source of the entire system), ii) a contribution from free ...

... S235 B From our observations, the near infrared spectrum of S235 B? is consistent with a reddened stellar photosphere with a moderate NIR excess (see Figure 7). ...
... From the two J and H measurements alone, assuming that in these two bands the stellar photosphere emission extincted by the circum stellar material dominates the measured flux, we would estimate a visual extinction greater than 15 magnitudes. ...

... Note that the derivation of the minimum mass assumes that all the observed emission at Kband is due to the stel lar photosphere (i.e. the infrared excess is not considered and corrected for). ...
