Eridanus IV: an Ultra-Faint Dwarf Galaxy Candidate Discovered in the DECam Local Volume Exploration Survey
W. Cerny, A. B. Pace, A. Drlica-Wagner +29
We present the discovery of a candidate ultra-faint Milky Way satellite, Eridanus IV (DELVE J05050931), detected in photometric data from the DECam Local Volume Exploration surv…
Metallicities from high resolution spectra of 49 RR Lyrae Variables
Christina K. Gilligan, Brian Chaboyer, Massimo Marengo +12
Accurate metallicities of RR Lyrae are extremely important in constraining period-luminosity-metallicity relationships (PLZ), particularly in the near-infrared. We analyse 69 high-…
The DECam Local Volume Exploration Survey: Overview and First Data Release
A. Drlica-Wagner, J. L. Carlin, D. L. Nidever +67
The DECam Local Volume Exploration survey (DELVE) is a 126-night survey program on the 4-m Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile. DELVE seeks to…
Evolutionary and pulsation properties of Type II Cepheids
G. Bono, V. F. Braga, G. Fiorentino +7
We discuss the observed pulsation properties of Type II Cepheids (TIICs) in the Galaxy and Magellanic Clouds. The period (P) distributions, luminosity amplitudes and population rat…
On the Metamorphosis of the Bailey diagram for RR Lyrae stars
G. Bono, V. F. Braga, J. Crestani +37
We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first overtone (9 RRc) mode. We…
Gaia RR Lyrae Stars in Nearby Ultra-Faint Dwarf Satellite Galaxies
A. Katherina Vivas, Clara Martínez-Vázquez, Alistair Walker
We search for RR Lyrae stars in 27 nearby ( kpc) ultra-faint dwarf satellite galaxies using the Gaia DR2 catalog of RR Lyrae stars. Based on proper motions, magnitudes and lo…
