High impact work by SIfA astronomers featured by AAS

6 August 2015

The American Astronomical Society has compiled 15 high-impact astronomy research papers published in the past three years, including two authored by researchers in SIfA. The two papers made significant progress in quantitatively understanding the properties of stars using both observations and simulations. Knowledge of stellar properties is crucial for solving a wide range of astrophysical problems.

SIfA astronomer Dr Daniel Huber was the lead author on one of these papers, 'Fundamental Properties of Kepler Planet-candidate Host Stars using Asteroseismology', which determined the properties of the host stars of 66 exoplanet candidates. Accurate knowledge of the properties of the host star is crucial for determining the properties of its planets and this work allowed more confident classification of planet candidates. Dr Dennis Stello and Professor Tim Bedding were co-authors on this work.

Dr Stello was also a co-author on 'Modules for Experiments in Stellar Astrophysics (MESA): Planets, Oscillations, Rotation, and Massive Stars', work led by Bill Paxton from the Kavli Institute for Theoretical Physics, Santa Barbara. MESA is an open source software package which models stellar evolution. Dr Stello's contribution to MESA's asteroseismic capabilities has helped MESA become the most sophisticated software tool for modelling oscillating stars.

This is further recognition of the status of the asteroseismology group at SIfA, which is internationally recognised as a leader in its field.
