The extreme CNO-enhanced composition of the primitive iron-poor dwarf star J0815+4729
Jonay I. González Hernández, David S. Aguado, Carlos Allende Prieto +2
We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high-quality data allow us…
J0815+4729: A chemically primitive dwarf star in the Galactic Halo observed with Gran Telescopio Canarias
D. S. Aguado, J. I. González Hernández, C. Allende Prieto +1
We report the discovery of the carbon-rich ultra metal-poor unevolved star J0815+4729. This dwarf star was selected from SDSS/BOSS as a metal-poor candidate and follow-up spectrosc…
The Pristine survey I: Mining the Galaxy for the most metal-poor stars
Else Starkenburg, Nicolas Martin, Kris Youakim +22
We present the Pristine survey, a new narrow-band photometric survey focused on the metallicity-sensitive Ca H & K lines and conducted in the northern hemisphere with the wide-fiel…
No surviving evolved companions to the progenitor of supernova SN 1006
Jonay I. Gonzalez Hernandez, Pilar Ruiz-Lapuente, Hugo M. Tabernero +4
Type Ia supernovae are thought to occur as a white dwarf made of carbon and oxygen accretes sufficient mass to trigger a thermonuclear explosion. The accretion could occur sl…
