My name is Rodolfo Smiljanic.
I am an associate professor at the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences, in Warsaw, Poland. I am an expert on the determination of chemical abundances from high-resolution spectra of late-type stars. My research interests include stellar evolution, Galactic stellar populations, large spectroscopic surveys, stellar nucleosynthesis, and the chemical composition of planet-host stars.
My research group is called the SAGA Team. Click below to learn more about our projects.
The Cassegrain U-Band Efficient Spectrograph (CUBES) is a new near-UV low- (R ~ 6 000) and medium-resolution (R ∼ 20 000) spectrograph being built for the 8-m VLT and expected to be installed in 2029. I am the Polish national co-PI in the consortium (which counts also with partners in Italy, Brazil, Germany, the UK, and Slovenia).
The Wide-field Spectroscopic Telescope (WST) will be a 12-m telescope for multi-object spectroscopy. It will have a large field-of-view (3.1 deg2) and high multiplex (>30 000), with both medium and high resolution modes and a large integral field unit. I am part of the steering committee and co-leader of the Galactic science working group.
Gaia is a scientific spacecraft launched by the European Space Agency (ESA) that is making a three-dimensional map of the Milky Way, by measuring the position and motion of more than a billion stars. Since November 2022, I am member of the the Gaia Science Team (GST), a committee that advises ESA, through the Gaia Project Scientist (Dr Johannes Sahlmann), on all top-level science performance, science policy and science organization aspects of the Gaia mission.
The High-Resolution Multi-Object Spectrograph (HRMOS) is a new instrument planned for the 8-m VLT. It will combine high-resolution (R ~ 80k) with multiplex between 50 in a FoV of 25 arcmin of diameter. I am member of the core science team that is developing the science case for HRMOS (since June 2020).
The paper "Carbon and nitrogen as indicators of stellar evolution and age. A homogeneous sample of 44 open clusters from the Gaia-ESO Survey" has been accepted for publication in A&A.
The leaders of all science working groups of the WST project met in Lausanne, Switzerland, to discuss the driving science cases for this future facility.
On September 26, the Ph.D. candidate André Rodrigo da Silva successfully defended his Ph.D. dissertation. André is the first student to conclude his doctorate at the SAGA Team.
The paper "Playing CHESS with stars. I. Search for similar stars in large spectroscopic data sets" has been accepted for publication in A&A.
The 42nd meeting of the Polish Astronomical Society (PTA for the acronym in Polish) took place in Warsaw, between 8-12 September. Four works with participation of the SAGA Team have been presented.
A short research note entitled "Testing the Solar Lithium Abundance with a Survival Model" has now been published at RNAAS.
Final Gaia-ESO catalogue of astrophysical parameters (DR5.1). Published on 07 Jul 2023 at the ESO data archive. A total of 114,916 stars encompassing all major components of the Milky Way.
Across the Universe is a book that presents our Institute (CAMK/PAN), its history, facilities, research groups and collaborations. Look for info of our group under "The Gaia-ESO Survey (and beyond)".
In June 2020, a short interview about CUBES was published at the news portal of the Polish Academy of Sciences (the text is in Polish only).
"Research should be conducted with honesty and integrity" and "All professional interactions should be conducted with consideration and respect". Between 2016-2018, I was part of the working group that elaborated the Ethics Statement and Guidelines for Good Practice of the European Astronomical Society.
COIN is a working group within the International Astrostatistics Association (IAA), that aims to foster the collaboration between astronomers, cosmologists, statisticians and machine learning experts.
The Working Group on Stellar Spectral Libraries was established within commission G5 of the IAU. The WG was tasked with carrying-on an inventory of the different attempts made to explain the discrepancies among different libraries, and summarize recommendations for actions that would improve the situation.
