    The Star Formation History of the Local Group Dwarf Elliptical Galaxy NGC 185. I. Stellar Content
    We present VI CCD photometry of ~16,000 stars in a 7.2′ x 7.2′ field of the Local Group dwarf elliptical galaxy NGC 185. The resulting VI color-magnitude...

    The Star Formation History of the Local Group Dwarf Elliptical Galaxy NGC 185. II. Gradients in the Stellar Population
    The star formation history of the dwarf elliptical galaxy NGC 185, together with its spatial variations, has been investigated for old, intermediate-age, and...

    The Star Formation History of the Local Group Dwarf Galaxy Leo I
    We present a quantitative analysis of the star formation history (SFH) of the Local Group dSph galaxy Leo I, from the information in its Hubble Space Telescope...

    The Star Formation History of the Pegasus Dwarf Irregular Galaxy
    The star formation history (SFH) of the Pegasus dIr, a likely Local Group member at 0.95 Mpc from the Milky Way, is investigated. We characterize the SFH by two...

    The star formation history of the Sculptor dwarf spheroidal galaxy
    We present the star formation history (SFH) of the Sculptor dwarf spheroidal galaxy based on deep g, r photometry taken with Dark Energy Camera at the Blanco...
  • Publication
    The star formation history of the Sextans dwarf spheroidal galaxy: a true fossil of the pre-reionization era
    We present the star formation history (SFH) of the Sextans dwarf spheroidal galaxy based on deep archive B, I photometry taken with Suprime-Cam at Subaru...
  • Publication
    The star formation rates of QSOs
    We examine the far-infrared (FIR) properties of a sample of 5391 optically selected QSOs in the 0.5 < z < 2.65 redshift range down to log [νL ν, 2500(erg s -1)]...
  • Publication
    The star formation timescale of elliptical galaxies. Fitting [Mg/Fe] and total metallicity simultaneously
    The alpha element to iron peak element ratio, for example [Mg/Fe], is a commonly applied indicator of the galaxy star formation timescale (SFT) since the two...
  • Publication
    The star which has engulfed a planet
    The fragile and rare isotope 6Li has a spallative origin. It is rapidly destroyed in solar-type stars while fully preserved in low-mass brown dwarfs and planets...
