Hello! My name is Vinicius [v-knee-see-uh-s] Placco and I am an Associate Astronomer at the NSF National Optical-Infrared Astronomy Research Laboratory (NSF NOIRLab). I work in the US National Gemini Office (US NGO | @usngo), which is a group within the Community Science and Data Center (CSDC) at the NOIRLab. Here you will find details about my research, publications, CV, side projects, and much more! My contact information is provided below.


My current research focuses on establishing observational constraints on the origins of the chemical elements in the Galaxy and the Universe through spectroscopic analysis of low-metallicity stars. Below you can find an interactive plot with a few selected synthetic spectra for stars with different metallicities ([Fe/H] - upper panel) and different carbon abundances ([C/Fe] - lower panel). All the spectra have the same effective temperature (Teff = 5250K) and surface gravity (logg=2.5). More details soon!
