RESEARCH INTERESTS
Time-varying celestial phenomena represent one of the most substantial sources of astrophysical information, and their study has led to many fundamental discoveries in modern astronomy. My interests in stellar astrophysics develop along three independent, yet connected, research lines that have as common background the study of variable stars (e.g., 2017NatAs, 1E, 166P, 2017ApJ, 844, 159C, 2015A&A...573A.100F). As such, it is the combined result of a profound and long-standing interest in i) panchromatic studies of stellar variability phenomena, ii) specific observing techniques (e.g., time-resolved photometry and medium-to-high resolution spectroscopy); and iii) development, optimization and intense use of optical and infrared (IR) astronomical instrumentation at small, medium, and large telescopes. Specifically, my current research activity at the Dept. of Astronomy of Universidad de La Serena focuses on:
1) Symbiotic Stars: discovering and characterizing the symbiotic phenomenon in external galaxies (e.g., Heo, Angeloni, Di Mille et al. 2016; Angeloni et al. 2014b, Angeloni et al. 2011); studying the nature of the accreting white dwarfs in symbiotic binaries through a systematic investigation of very fast photometric variability (e.g., Angeloni et al. 2012); enlarging the symbiotic population by searching for new symbiotic candidates in our Local Group (Angeloni et al. 2019).
2) BOMBOLO: a new astronomical imager, accepted as Visitor Instrument at the SOAR 4m Telescope (Garcés et al., 2016, SPIE.9908E..4BG; Angeloni et al. 2014, RMxAC..44..206A).
3) Analysis and interpretation of the light curves obtained during the intensive variability campaign of the VVV ESO Public Survey, after completion of the preparatory VVV Templates Project (Angeloni et al. 2014a, Saito, Minniti, Angeloni et al. 2013).
