The Actinide-Boost Star LAMOST J122216.85-063345.2: A Detailed R-process Abundance Study with Gemini-S/GHOST
Miji Jeong, Young Sun Lee, Vinicius M. Placco +15
We present a detailed chemical-abundance analysis of an actinide-boost ((Th/Dy) = -0.74) star, LAMOST J122216.85-063345.2 (J1222), a very metal-poor ([Fe/H] = -2.45) halo st…
Type IIP supernova SN 2016X in radio frequencies
Roque Ruiz-Carmona, Itai Sfaradi, Assaf Horesh
Context: The study of radio emission from core-collapse supernovae (SNe) probes the interaction of the ejecta with the circumstellar medium (CSM) and reveals details of the mass-lo…
A systematic study of spiral density waves in the accretion discs of Cataclysmic Variables
R. Ruiz-Carmona, P. J. Groot, D. T. H. Steeghs
Spiral density waves are thought to be excited in the accretion discs of accreting compact objects, including Cataclysmic Variable stars (CVs). Observational evidence has been obta…
Analysis of spiral structure in the accretion disc of the novalike Cataclysmic Variable EC21178--5417
R. Ruiz-Carmona, Z. N. Khangale, P. A. Woudt +1
We present an extensive Doppler tomography study of the eclipsing novalike EC21178--5417, which exhibits the classic accretion disc signature in the form of double-peak emission li…
Discovery of 36 eclipsing EL CVn binaries found by the Palomar Transient Factory
J. van Roestel, T. Kupfer, R. Ruiz-Carmona +6
We report the discovery and analysis of 36 new eclipsing EL CVn-type binaries, consisting of a core helium-composition pre-white dwarf and an early-type main-sequence companion, mo…
