UGC 7639: A Dwarf Galaxy in the Canes Venatici I Cloud

Figure 6

(a) The evolution of the SFR predicted by our simulation for UGC 7639. The black vertical line corresponds to the galaxy age (8.6 Gyr; see text). (b) Gas accretion history (solid line), that is, the evolution of the gas mass inside a radius of 50 kpc on the r-band image luminous center of the galaxy from our selected SPH simulations. The (blue) dashed and the (red) dotted lines correspond to the gas with temperatures 10⁴ K and 10⁶ K, respectively.
