Abstract:
We have determined extinction corrections for a sample of 441
late-type stars in the inner Galaxy, which we previously searched for
SiO maser emission, using the 2MASS near-infrared photometry of the
surrounding stars. From this, the near-infrared extinction law is
found to be approximated by a power law
A_lambda_prop.tolambda^-1.9+/-0.1^. Near- and mid-infrared
colour-colour properties of known Mira stars are reviewed. From the
distribution of the dereddened infrared colours of the SiO target
stars we infer mass-loss rates between 10^-7^ and 10^-5^M_sun_/yr.
Description:
A catalogue of interstellar extinction estimates is presented for a
sample of 441 stars which we previously searched for SiO maser
emission (Messineo et al. 2002, Cat. J/A+A/393/115,
2004, Cat. J/A+A/418/103). The identification source numbers
(e.g #99) are taken from Table 2 (86 GHz SiO maser detections) and
Table 3 (non-detections) in Messineo et al. (2002, J/A+A/393/115),
and are the same as those used in Table 2 by Messineo et al. (2004,
J/A+A/418/103).
We estimated a mean extinction Aks in the direction of each SiO star
by using 2MASS stars within 2-4 arcmin of each SiO star. We therefore
shifted the colours of field stars (J-Ks) and (H-Ks) versus Ks
magnitudes along the reddening vector onto the reference RGB. For
fields with Aks<1.6mag table3 lists the extinction values determined
from the (Ks,J-Ks) plane, at larger extinction values those from the
(Ks,H-Ks) plane. For 46 "foreground" SiO targets Aks is an extinction
estimate obtained by directly shifting the colours of the SiO target
on the (H,Ks)-[15] colour-colour sequence.
The total (circumstellar plus interstellar) extinction of each SiO
target is measured by assuming a stellar photospheric (J-Ks)0 colour
of 1.4mag and an (H-Ks)0 colour of 0.5mag.
A group of 46 mostly very bright target stars (Ks<6.0), marked with
flag Fg=1, have total extinctions lower (a least 1 sigma) than the
"field" extinction and are therefore likely to be foreground objects.
