Job Advertisement: Closing Date 31st March 2017
A call is ongoing for a PhD project on *"Ensemble asteroseismology of
solar-type stars with the NASA TESS mission"* (see abstract below).
Details on the application procedure can be found at
http://phd-space.iastro.pt/?page_id=1045. This PhD project has been made
available in the context of the PhD::SPACE Program, funded by the FCT PD
Program Initiative (Portugal). The *deadline* for applications is the
*31st of March 2017*.
The student will be based at Instituto de Astrofísica e Ciências do
Espaço — University of Porto (Portugal). It is nonetheless expected that
the student will spend one-third of their time between the University of
Göttingen (Germany) and Aarhus University (Denmark).
Further information on the project can be directly obtained from Dr.
Tiago Campante ([log in to unmask]), Dr. Mikkel Lund
([log in to unmask]) or Dr. Margarida Cunha ([log in to unmask]).
*Abstract:* The Transiting Exoplanet Survey Satellite (TESS) is a NASA
space mission, with launch scheduled for March 2018, that will perform
an all-sky survey for planets transiting bright nearby stars.
Furthermore, TESS's excellent photometric precision will enable
asteroseismology, the detailed study of stars by the observation of
their natural, resonant oscillations. Asteroseismology is proving to be
particularly relevant for the study of solar-type stars (i.e., low-mass,
main-sequence stars and cool subgiants), in great part due to the
exquisite photometric data made available by NASA's Kepler space
telescope and, more recently, by the repurposed K2 mission. In extending
the legacy of Kepler/K2, the main goal of this project will be to
perform an ensemble asteroseismic study of bright solar-type stars that
reside in the solar neighborhood, making use of data collected by TESS
during its 2-year primary mission. To that end, we propose an end-to-end
PhD project that will provide the student with skills in photometric
time-series preparation from pixel data, asteroseismic data analysis and
stellar modeling techniques. The implications of this project are
far-reaching. The proposed research will provide a well characterized
sample of benchmark solar-type stars to be used in studies of
exoplanetary systems and of the chemical evolution of the solar
neighborhood, the latter of which will impact on Galactic archaeology
studies.
