Atmospheric asymmetries in WASP-121 b revealed by rotational transits detected with JWST

Cyril Gapp, Aurélien Falco, Thomas M. Evans-Soma +6

Close-in exoplanets are tidally locked to their host star and thus exhibit extreme atmospheric temperature gradients. It has been theorized that the fraction of star light absorbed…

Calibration of an Analog-to-Digital Conversion Nonlinearity in JWST/NIRISS

Shashank Dholakia, Shishir Dholakia, Benjamin J. S. Pope +4

We quantify an unusual flux-dependent systematic which is periodic in raw counts in flight data from the James Webb Space Telescope's Near Infrared Imager and Slitless Spectrograph…

Analytic Interferometry of Rotating Stellar Surfaces

Shashank Dholakia, Benjamin J. S. Pope

The surfaces of rotating stars serve as a window into their interiors, magnetic dynamos, and are important in other areas including exoplanet discovery and atmospheric characteriza…

The Serpent Eating Its Own Tail: Dust Destruction in the Apep Colliding-Wind Nebula

Ryan M. T. White, Benjamin J. S. Pope, Peter G. Tuthill +5

Much of the carbonaceous dust observed in the early universe may originate from colliding wind binaries (CWBs) hosting hot, luminous Wolf-Rayet (WR) stars. Downstream of the shock…

A General, Differentiable Transit Model for Ellipsoidal Occulters: Derivation, Application, and Forecast of Planetary Oblateness and Obliquity Constraints with JWST

Shashank Dholakia, Shishir Dholakia, Benjamin J. S. Pope

Increasingly precise space-based photometry uncovers higher-order effects in transits, eclipses and phase curves which can be used to characterize exoplanets in novel ways. The sub…

Efficient and precise transit light curves for rapidly-rotating, oblate stars

Shashank Dholakia, Rodrigo Luger, Shishir Dholakia

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…

Constraining Orbital Periods from Nonconsecutive Observations: Period Estimates for Long-Period Planets in Six Systems Observed by K2 During Multiple Campaigns

S. Dholakia, Andrew W. Mayo, Courtney D. Dressing

Most planetary discoveries with the K2 and TESS missions are restricted to short periods because of the limited duration of observation. However, the re-observation of sky area all…
