VIPER: A high-resolution multimode fiber-fed VIPA spectrograph concept for characterizing exoplanet atmospheric escape

Kavli Affiliate: David Charbonneau | Summary:An increasing number of applications in exoplanetary science require spectrographs with high resolution and high throughput without the need for a broad spectral range. Examples include the search for biosignatures through the detection of the oxygen A-band at 760 nm, and the study of atmospheric escape through the helium 1083 […]

Metallicities from High-Resolution TRES Spectra with uberMS: Performance Benchmarks and Literature Comparison

Kavli Affiliate: David Charbonneau | Summary:As the field of exoplanetary astronomy has matured, demand has grown for precise stellar abundances to probe subtle correlations between stellar compositions and planetary demographics. However, drawing population-level conclusions from the disparate measurements in the literature is challenging, with various groups measuring metallicities using bespoke codes with differing line lists, […]

Spot-Crossing Variations Confirm a Misaligned Orbit for a Planet Transiting an M Dwarf

Kavli Affiliate: David Charbonneau | Summary:TOI-3884~b is an unusual 6.4~R$_oplus$ planet orbiting an M4 host, whose transits display large and persistent spot-crossing events. We used the textitTierras Observatory to monitor both the long-term photometric variability of TOI-3884 and changes in the spot-crossing events across multiple transits of the planet. We show that the star rotates […]

Data-driven quasiconformal morphodynamic flows

Kavli Affiliate: L. Mahadevan | First 5 Authors: Salem Mosleh, Gary P. T. Choi, L. Mahadevan, , | Summary: Temporal imaging of biological epithelial structures yields shape data at discrete time points, leading to a natural question: how can we reconstruct the most likely path of growth patterns consistent with these discrete observations? We present […]

Control of flow behavior in complex fluids using automatic differentiation

Kavli Affiliate: Michael Brenner | First 5 Authors: Mohammed Alhashim, Kaylie Hausknecht, Michael Brenner, , | Summary: Inverse design of complex flows is notoriously challenging because of the high cost of high dimensional optimization. Usually, optimization problems are either restricted to few control parameters, or adjoint-based approaches are used to convert the optimization problem into […]

Mechanics and wrinkling patterns of pressurized bent tubes

Kavli Affiliate: Ariel Amir | First 5 Authors: Cesar L. Pastrana, Luyi Qiu, John W. Hutchinson, Ariel Amir, Ulrich Gerland | Summary: Take a drinking straw and bend it from its ends. After sufficient bending, the tube buckles forming a kink, where the curvature is localized in a very small area. This instability, known generally […]
