Compact multi-planet systems are more common around metal poor hosts

John M. Brewer, Songhu Wang, Debra A. Fischer +1

In systems with detected planets, hot-Jupiters and compact systems of multiple planets are nearly mutually exclusive. We compare the relative occurrence of these two architectures…

STARRY: Analytic Occultation Light Curves

Rodrigo Luger, Eric Agol, Daniel Foreman-Mackey +3

We derive analytic, closed form, numerically stable solutions for the total flux received from a spherical planet, moon or star during an occultation if the specific intensity map…

A Robust Method to Measure Centroids of Spectral Lines

Richard Teague, Daniel Foreman-Mackey

Measuring the centroid of a spectral line is a common problem in astronomy. Many methods have been devised to overcome limitations due to either noise in the spectra or asymmetric…

The orbital eccentricity of small planet systems

Vincent Van Eylen, Simon Albrecht, Xu Huang +8

We determine the orbital eccentricities of individual small Kepler planets, through a combination of asteroseismology and transit light-curve analysis. We are able to constrain the…

A Kinematical Detection of Two Embedded Jupiter Mass Planets in HD 163296

Richard Teague, Jaehan Bae, Edwin Bergin +2

We present the first kinematical detection of embedded protoplanets within a protoplanetary disk. Using archival ALMA observations of HD 163296, we demonstrate a new technique to m…

Inference of stellar parameters from brightness variations

Melissa K. Ness, Victor Silva Aguirre, Mikkel N. Lund +4

It has been demonstrated that the time variability of a star's brightness at different frequencies can be used to infer its surface gravity, radius, mass, and age. With large sampl…
