[ASA] Planets in Pecular Places - Save the Date: April 5-6, University of Sydney

[Benjamin Pope]

Dear John,

We would love it if you could pass this email on to the ASA exploder,
announcing a Hunstead Workshop at the University of Sydney April 5-6 this
year.

-----------------

To all exoplanet and star enthusiasts!

Thanks to the generosity of the Hunstead Gift, the Sydney Institute for
Astronomy (SIfA) at the University of Sydney will be hosting a two-day
symposium on April 5-6 on the subject of Planets in Peculiar Places -
perhaps the oldest but least studied branch of current exoplanet science,
covering planets around pulsars, red giants, white dwarfs, subdwarfs, and
hot main sequence stars. With the launch of the Transiting Exoplanet Survey
Satellite (TESS) coming up this is an ideal time to consider the science
goals and technology requirements for understanding planetary systems
outside the typical search space of FGK dwarfs.

Save the date! Website and registration details to follow in a second
announcement.

We hope you will be able to join us.

Kind regards,

Simon Murphy

Title: Planets in Peculiar Places: Exoplanets in the Lives and Afterlives
of Massive Stars

Abstract: Exoplanetary science since 1995 has been dominated by a race to
find the most Earth-like planets around the most Sun-like stars, but there
are much stranger worlds in much more exotic systems than this. Indeed, the
first exoplanets were discovered orbiting a neutron star, detected by
pulsar timing, and the first evidence of exoplanets, not recognized at the
time, came from metal pollution in white dwarf atmospheres. Recent
discoveries have revealed planets transiting red giant stars, or discovered
through timing the pulsations of main sequence stars. While we are
beginning to have a clear picture of the formation and evolution of
planetary systems around solar-like main sequence stars, we are in the dark
about planets around more massive stars in their lives and various
afterlives. Planetary system evolution around hot stars and binaries is
poorly-understood, because such stars are often variable and their planets
hard to detect; the worlds orbiting red giants are relics from which we can
decipher this hidden story. How do planetary systems change as stars evolve
in different mass regimes? How are planet occurrence rates affected by
stellar evolution? The origin of the white dwarf planets is similarly
murky: are these left over from the original system, or second-generation
planets formed afresh around the white dwarf? And how are the pulsar
planets formed? The Sydney Institute for Astronomy is hosting a Hunstead
workshop to bring together the vibrant and diverse community beginning to
address these questions, interleaving talks by observers and theorists,
focusing especially on the Australian contributions to asteroseismology and
transit searches (Kepler, TESS), radial velocity (e.g. Veloce, RHEA,
Minerva), pulsar timing, direct imaging, and large spectroscopic surveys,
and how we can tie these efforts together to understand the strange physics
of planets in these peculiar places.
