Abstract:
We investigate the star formation activity in the molecular complex
associated with the Galactic HII region Sh2-90.
We obtain the distribution of the ionized and cold neutral gas using
radio-continuum and Herschel observations. We use near-infrared and
Spitzer data to investigate the stellar content of the complex. We
discuss the evolutionary status of embedded massive young stellar
objects (MYSOs) using their spectral energy distribution.
Description:
To identify YSOs, we observed the Sh2-90 complex at NIR bands with
WIRCAM instrument at the 3.6m CHFT telescope, and supplement these
observations with the GLIMPSE point source catalog from Benjamin et
al. (2003PASP..115..953B 2003PASP..115..953B, Cat. II/293). The complex were observed at
NIR bands on 2006 July 8 using the WIRCAM camera on the CHFT 3.6m
telescope. This table includes photometry of the identified YSOs at
NIR and Spitzer-IRAC bands. In the table, the columns one and two give
coordinates of the YSOs. The following six columns provide the JHK
magnitudes and associated errors obtained in our observations, while
the next eight columns list the Spitzer-IRAC magnitudes and associated
errors. The last column provides the sequence of the table and the
sequence number 1 to 21, 22 to 55 and 56 to 129 corresponds to the
Class I, Class II and NIR-excess YSOs, respectively.
