Scientific paper

Based on Chandra observations, we performed a comprehensive analysis of NGC 4342, an optically faint early-type galaxy in the outskirts of the Virgo cluster. This galaxy hosts an unusually bright (L_X˜10^{40} erg/s), hot (kT˜0.56 keV) X-ray corona. However, the low stellar mass of NGC 4342 should not be sufficient to gravitationally bind such a significant amount of hot gas. Therefore, NGC 4342 is a truly unique and curious object. With a tenuously bound, but bright corona, NGC 4342 is ``the canary of the coal mine'' for sensing the presence of external gas in its local environment. Our goal is to understand the origin and nature of the unusually large gas mass surrounding NGC 4342, and measure the properties of the external medium producing the observed gas distortions.
