exoplanet: Gradient-based probabilistic inference for exoplanet data & other astronomical time series
Daniel Foreman-Mackey, Rodrigo Luger, Eric Agol +13
"exoplanet" is a toolkit for probabilistic modeling of astronomical time series data, with a focus on observations of exoplanets, using PyMC3 (Salvatier et al., 2016). PyMC3 is a f…
Linearized Field Deblending: PSF Photometry for Impatient Astronomers
Christina Hedges, Rodrigo Luger, Jorge Martinez Palomera +2
NASA's Kepler, K2 and TESS missions employ Simple Aperture Photometry (SAP) to derive time-series photometry, where an aperture is estimated for each star, and pixels containing ea…
Multi-Wavelength Photometry Derived from Monochromatic Kepler Data
Christina Hedges, Rodrigo Luger, Jessie Dotson +2
The Kepler mission has provided a wealth of data, revealing new insights in time-domain astronomy. However, Kepler's single band-pass has limited studies to a single wavelength. In…
The Pointing Limits of Transiting Exoplanet Light Curve Characterization with Pixel Level De-correlation
Nicholas Saunders, Rodrigo Luger, Rory Barnes
We present scope (Simulated CCD Observations for Photometric Experimentation), a Python package to create a forward model of telescope detectors and simulate stellar targets with m…
eleanor: An open-source tool for extracting light curves from the TESS Full-Frame Images
Adina D. Feinstein, Benjamin T. Montet, Daniel Foreman-Mackey +8
During its two year prime mission the Transiting Exoplanet Survey Satellite (TESS) will perform a time-series photometric survey covering over 80% of the sky. This survey comprises…
Wobble: A Data-driven Analysis Technique for Time-series Stellar Spectra
Megan Bedell, David W. Hogg, Daniel Foreman-Mackey +2
In recent years, dedicated extreme-precision radial velocity (EPRV) spectrographs have produced vast quantities of high-resolution, high-signal-to-noise time-series spectra for bri…
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…
Linear models for systematics and nuisances
Rodrigo Luger, Daniel Foreman-Mackey, David W. Hogg
The target of many astronomical studies is the recovery of tiny astrophysical signals living in a sea of uninteresting (but usually dominant) noise. In many contexts (i.e., stellar…
An update to the EVEREST K2 pipeline: Short cadence, saturated stars, and Kepler-like photometry down to Kp = 15
Rodrigo Luger, Ethan Kruse, Daniel Foreman-Mackey +2
We present an update to the EVEREST K2 pipeline that addresses various limitations in the previous version and improves the photometric precision of the de-trended light curves. We…
