Waves inside Stars: Theory, Simulations, Observational Signatures, and Lab
Splinter session, Monday 31 August, 10h - 12h30, during
SOLARNET III / HELAS VII / SpaceInn Conference "The Sun, the stars, and solar-stellar relations"

Waves are as ubiquitous in stars as they are on Earth. Just as on Earth, waves
can transport angular momentum and mix species within stellar interiors,
steering their rotational and chemical evolution. Waves also set up standing
modes which can be observed through helio- and asteroseismology.
Helioseismology has revolutionized our picture of the Sun, constraining the
internal rotation profile and convective undershooting in the solar interior.
Asteroseismology is not far behind, recently constraining core-envelope
differential rotation and core convective overshooting in more massive stars.
Indeed, the observations of waves through helio- and asteroseismology places the
tightest constraints on the dynamical evolution those same waves induce.
This 2.5 hour splinter session aims to bring together researchers doing theory,
simulations, and observations of waves in stars (gravity, pressure and mixed)
with the hope that the synergy between the three (often disparate) fields could
lead to tests and comparisons which would further our understanding of stellar
interiors. Moreover, we include also studies of wave generation by convection
in laboratory experiments to search for connections between those and stellar
physics. We begin this session with four short talks on each of the sub-topics
and will then continue with a guided discussion on how these fields can work
together to advance our understanding.
