Multiwavelength Study of Star Formation in NGC 3413

Author : SP Deshmukh and AU Patil

Abstract :

Early type galaxies (ETG), have regular impression of being “Red and Dead” with no ongoing star formation activity in it. But recent multiwavelength study of considerable fraction of ETGs suggests the active star formation in it. In the present work, we studied a lenticular galaxy NGC 3413. We performed optical spectroscopy and Spectral Energy Distribution study of target galaxy. It is found that, NGC 3413 holds an ongoing star formation activity and most of the stellar population of the galaxy is having age less than 2.5 Gyr. The star formation rate for target galaxy is found to be 0.64 Mʘ/year. SED predicts the presence of moderate amount of dust in NGC 3413 with dust mass 9.842 x 105 Mʘ.
