Víctor Silva Aguirre, Associate Professor
Víctor’s main field of expertise is asteroseismology of main-sequence and red giant stars, and deriving accurate stellar properties with implications in a wide range of areas in astrophysics. His research interests include theoretical stellar structure and evolution, asteroseismic inference in solar-like oscillators, characterisation of exoplanet host stars and architecture of planetary systems, composite stellar populations in the Milky Way, and Galactic archaeology.

Víctor holds various leading positions in large international consortiums related to space missions such as Kepler, K2, TESS, and PLATO, as well as in large-scale ground based surveys such as APOGEE and SAGA. He is also the recipient of the Villum Young Investigators Programme grant, the Sapere Aude initiative from the Independent Research Fund Denmark, and the Aarhus University Research Foundation starting grant.


Jakob Rørsted Mosumgaard, Postdoc
Jakob’s main research interest is stellar modelling of stars showing solar-like oscillations. His primary focus is to improve the current models by the use of 3D hydrodynamical simulations of stellar atmospheres. Specifically, he is investigating the atmosphere in stellar structure models as well as the treatment of stellar convection.

Jakob is also generally interested in grid-based modelling and it’s use in combination with asteroseismology to determine stellar parameters. Jakob is the main administrator of the different codes used in the group.

Emanuele Spitoni, Postdoc
Emanuele’s field of research is Galactic Astroarchaeology using chemical evolution models. Finding signatures for the formation and evolution of our Galaxy from observed abundances is a fundamental step to understand the evolution of the Universe. By interpreting trends in the abundance ratios observed in stellar populations and by using chemical evolution models, he studies the detailed nucleosynthesis from low and intermediate mass stars, Type Ia SNe (originating from white dwarfs in binary systems) and Ib/c and II SNe (originating from core-collapse of massive stars) in presence of infall, outflow, radial gas flows, and even stellar migration.

Kuldeep Verma, Postdoc
Kuldeep’s current research is focused on the study of solar-like stars using the asteroseismic data from Kepler satellite, grids of theoretical stellar models, and using the glitch analysis. He uses sophisticated numerical techniques, statistical tools, and machine learning approaches to learn and improve the physics of stellar interiors and also derive precisely and accurately the fundamental stellar properties, e.g., the mass, radius, age, helium abundance, etc.

Camilla Borre, PhD student
Camilla is interested in the study of stars and how they can be used to learn more about the Galaxy and the universe.

Her research revolves around determining the time of major merger events in the Milky Ways history by analysing the very bright red giant stars using asteroseismology. Through a combination of observations and stellar modelling, she determines the ages of the stars which, in combination with other observables, can be used to understand the history of the Galaxy.

Luisa Fernanda Rodriguez Diaz, PhD student
Luisa is a new PhD student who is working on the expansion of a 3D hydrodynamical grid of model atmospheres for late-type stars. Specifically, she is learning how the simulations are made, how can they be improved and how to run them.

Amalie Stokholm, PhD student
Amalie uses asteroseismology and stellar modelling to study a large sample of targets in order to unravel the history of our Galaxy, the Milly Way.

In particular, she studies red giant stars in the disk(s) of the Milky Way and looks for patterns related to the merger history of the Galaxy.

Tim White, Postdoc (Currently at University of Sydney)
Tim uses the most sensitive observational tools of modern stellar astrophysics to determine the properties of stars with the utmost precision. Oscillations in stars can be detected using sensitive photometric measurements, such as those made with NASA’s Kepler and K2 Missions, from which stellar properties such as radius, mass, and age can be determined using asteroseismology.

Additionally, Tim uses long-baseline optical interferometry to directly measure the sizes and effective temperatures of stars. Precise and accurate measurements of fundamental stellar properties are crucial for testing stellar models, through which we enhance our understanding of stellar structure and evolution.

Mikkel Nørup Lund, Postdoc (Currently at Stellar Astrophysics Centre, Aarhus University)
Mikkel’s main research interest is focused around the study of solar-type stars using asteroseismology. This includes the extraction of information from stellar oscillation modes for use in stellar modelling efforts, the assessment of rotation and activity, as well as the determination of the spin-orbit alignment exoplanet host stars.

Mikkel is also interested in the utilisation of photometry from space based missions such as the NASA Kepler and K2 missions for use in, for instance, asteroseismology. Mikkel is involved in the preparatory work for the upcoming NASA TESS mission, with emphasis on light curve preparation and data calibration

Ditte Slumstrup, Postdoc (Currently at ESO, Chile)
Ditte’s main research interest is optical spectroscopy of red giants. She is currently working on characterizing systematic differences in the analysis of optical spectra between different methods utilizing precise atmospheric parameters from other fields, such as asteroseismology.

Ditte is also interested in the chemical evolution and structure of the Milky Way, working with different chemical abundance trends with stellar ages.
