A single power law for the TRAPPIST-1 flare distribution across four orders of magnitude in energy
Valeriy Vasilyev, Alexander I. Shapiro, Nadiia Kostogryz +10
TRAPPIST-1 is an ultra-cool dwarf that flares frequently. These flares shape the surrounding planets' high-energy irradiation environments, with consequences for atmospheric chemis…
JWST-TST High Contrast: Spectroscopic Characterization of the Benchmark Brown Dwarf HD 19467 B with the NIRSpec Integral Field Spectrograph
Kielan K. W. Hoch, Christopher A. Theissen, Travis S. Barman +14
We present the atmospheric characterization of the substellar companion HD 19467 B as part of the pioneering JWST GTO program to obtain moderate resolution spectra (R2,700, 3…
Stellar Surface Magnetic Fields Impact Limb Darkening
Nadiia M. Kostogryz, Alexander I. Shapiro, Veronika Witzke +8
Stars appear darker at their limbs than at their disk centers because at the limb we are viewing the higher and cooler layers of stellar photospheres. Limb darkening derived from s…
Complex Rotational Modulation of Rapidly Rotating M-Stars Observed with TESS
Z. Zhan, M. N. Günther, S. Rappaport +23
We have searched for short periodicities in the light curves of stars with cooler than 4000 K made from 2-minute cadence data obtained in TESS sectors 1 and 2. Herein…
