The Serpent Eating Its Own Tail: Dust Destruction in the Apep Colliding Wind Nebula Open
Much of the carbonaceous dust observed in the early Universe may originate from colliding wind binaries (CWBs) hosting hot, luminous Wolf–Rayet (W-R) stars. Downstream of the shock between the stellar winds there exists a suitable environm…

A General, Differentiable Transit Model for Ellipsoidal Occulters: Derivation, Application, and Forecast of Planetary Oblateness and Obliquity Constraints with JWST Open
Increasingly precise space-based photometry uncovers higher-order effects in transits, eclipses, and phase curves that can be used to characterize exoplanets in novel ways. The subtle signature induced by a rotationally deformed exoplanet …

Efficient and Precise Transit Light Curves for Rapidly Rotating, Oblate Stars Open
We derive solutions to transit light curves of exoplanets orbiting rapidly rotating stars. These stars exhibit significant oblateness and gravity darkening, a phenomenon where the poles of the star have a higher temperature and luminosity …

Efficient transit light curves for oblate and rapidly rotating stars Open
Exoplanets that transit rapidly-rotating stars can be a unique tool to learn about the dynamical history of exoplanet systems photometrically. Two rotational effects on such stars are oblateness and gravity darkening, where the poles are h…

Constraining Orbital Periods from Nonconsecutive Observations: Period Estimates for Long-period Planets in Six Systems Observed by K2 During Multiple Campaigns Open
Most planetary discoveries with the K2 and Transiting Exoplanet Survey Satellite ( TESS ) missions are restricted to short periods because of the limited duration of observation. However, the re-observation of sky area allows for the detec…
