Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis
Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31
The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…
A close-in giant planet escapes engulfment by its star
Marc Hon, Daniel Huber, Nicholas Z. Rui +39
When main-sequence stars expand into red giants, they are expected to engulf close-in planets. Until now, the absence of planets with short orbital periods around post-expansion, c…
Simplifying asteroseismic analysis of solar-like oscillators: An application of principal component analysis for dimensionality reduction
M. B. Nielsen, G. R. Davies, W. J. Chaplin +5
The asteroseismic analysis of stellar power density spectra is often computationally expensive. The models used in the analysis may use several dozen parameters to accurately descr…
Near-Core Acoustic Glitches are Not Oscillatory: Consequences for Asteroseismic Probes of Convective Boundary Mixing
Christopher J. Lindsay, J. M. Joel Ong, Sarbani Basu
Asteroseismology has been used extensively in recent years to study the interior structure and physical processes of main sequence stars. We consider prospects for using pressure m…
ASAS-SN Sky Patrol V2.0
K. Hart, B. J. Shappee, D. Hey +13
The All-Sky Automated Survey for Supernovae (ASAS-SN) began observing in late-2011 and has been imaging the entire sky with nightly cadence since late 2017. A core goal of ASAS-SN…
Revisiting the Red-giant Branch Hosts KOI-3886 and Draconis. Detailed Asteroseismic Modeling and Consolidated Stellar Parameters
Tiago L. Campante, Tanda Li, J. M. Joel Ong +23
Asteroseismology is playing an increasingly important role in the characterization of red-giant host stars and their planetary systems. Here, we conduct detailed asteroseismic mode…
Mode Mixing and Rotational Splittings: II. Reconciling Different Approaches to Mode Coupling
J. M. Joel Ong, Charlotte Gehan
In the mixed-mode asteroseismology of subgiants and red giants, the coupling between the p- and g-mode cavities must be understood well in order to derive localised estimates of in…
Evolutionary and Observational Properties of Red Giant Acoustic Glitch Signatures
David Saunders, Joel Ong, Sarbani Basu
While solar-like oscillations in red giants have been observed at massive scale by the Kepler mission, few features of these oscillation mode frequencies, other than their global p…
TESS Asteroseismic Analysis of HD 76920: The Giant Star Hosting An Extremely Eccentric Exoplanet
Chen Jiang, Tao Wu, Adina D. Feinstein +30
The Transiting Exoplanet Survey Satellite (TESS) mission searches for new exoplanets. The observing strategy of TESS results in high-precision photometry of millions of stars acros…
