The GALAH Survey: Dependence of elemental abundances on age and metallicity for stars in the Galactic disc
Sanjib Sharma, Michael R. Hayden, Joss Bland-Hawthorn +24
Using data from the GALAH survey, we explore the dependence of elemental abundances on stellar age and metallicity among Galactic disc stars. We find that the abundance of most ele…
The GALAH Survey: Chemical Clocks
Michael R. Hayden, Sanjib Sharma, Joss Bland-Hawthorn +27
Previous studies have found that the elemental abundances of a star correlate directly with its age and metallicity. Using this knowledge, we derive ages for a sample of 250,000 st…
KELT-20b: A giant planet with a period of P~ 3.5 days transiting the V~ 7.6 early A star HD 185603
Michael B. Lund, Joseph E. Rodriguez, George Zhou +46
We report the discovery of KELT-20b, a hot Jupiter transiting a V~7.6 early A star with an orbital period of P~3.47 days. We identified the initial transit signal in KELT-North sur…
The dynamical structure of HR 8799's inner debris disk
Bruna Contro, Rob Wittenmyer, Jonti Horner +1
The HR 8799 system, with its four giant planets and two debris belts, has an architecture closely mirroring that of our Solar system where the inner, warm asteroid belt and outer,…
