We report the discovery of the second compact elliptical ( cE ) galaxy SDSS J 150634.27 + 013331.6 in the nearby NGC 5846 group by the Virtual Observatory ( VO ) workflow .
This object ( M _ { B } = -15.98 mag , R _ { e } = 0.24 kpc ) becomes the fifth cE where the spatially-resolved kinematics and stellar populations can be obtained .
We used archival HST WFPC2 images to demonstrate that its light profile has a two-component structure , and integrated photometry from GALEX , SDSS , UKIDSS , and Spitzer to build the multi-wavelength SED to constraint the star formation history ( SFH ) .
We observed this galaxy with the PMAS IFU spectrograph at the Calar-Alto 3.5m telescope and obtained two-dimensional maps of its kinematics and stellar population properties using the full-spectral fitting technique .
Its structural , dynamical and stellar population properties suggest that it had a massive progenitor heavily tidally stripped by NGC 5846 .
