Abstract:We present a study on the detailed chemical abundances of five new relatively bright r-processenhanced stars that were initially observed as part of the SDSS/MARVELS pre-survey. These stars were selected, on the basis of their metallicities and carbon abundances, among a total of 60 stars, for high-resolution spectroscopic follow-up as part of the HESP-GOMPA survey (Hanle Echelle SPectrograph -Galactic survey Of Metal Poor stArs). Here we discuss the three new r-I and two new r-II stars found in this survey. W… Show more
