…We test the G280 grism mode on the hot Jupiter HAT-P-41b over two consecutive transits to determine its viability for the characterization of exoplanet atmospheres.… …We obtain a broadband transit depth precision of 29-33ppm and a precision of on average 200ppm in 10nm spectroscopic bins.…

IVOA Registry (Virtual Observatory)2021 · Astronomical catalogue

…The planet was observed in transit with Hubble STIS and WFC3 as part of the Hubble Panchromatic Comparative Exoplanet Treasury (PanCET) program, and we combine those data with warm… …Spitzer transit observations.…

IVOA Registry (Virtual Observatory)2014 · Astronomical catalogue

…The case is strengthened to a level of significance to 2.3{sigma} when transit-detected close-in planets are included.… …This is most likely because the RV-selected sample of stars is significantly less active than the field population of comparable stars, while the transit-selected sample is similarly…

IVOA Registry (Virtual Observatory)2020 · Astronomical catalogue

…We found that the average blueshifted emission of K2-18 decreases by 67%+/-18% during the transit of the planet compared to the pre-transit emission, tentatively indicating the presence… …This interpretation is not definitive because it relies on one partial transit.…

IVOA Registry (Virtual Observatory)2018 · Astronomical catalogue

…We present a catalog of cool dwarf targets (V-J>2.7, T_eff_~<4000 K) and their stellar properties for the upcoming Transiting Exoplanet Survey Satellite (TESS), for the purpose of determining… …TESS has the opportunity to search tens of thousands of nearby, cool, late K- and M-type dwarfs for transiting exoplanets, an order of magnitude more than current or previous transiting…

IVOA Registry (Virtual Observatory)2016 · Astronomical catalogue

…The search for transiting habitable exoplanets has broadened to include several types of stars that are smaller than the Sun in an attempt to increase the observed transit depth and… …We use archival Hubble Space Telescope data from the Cosmic Origins Spectrograph to search for transiting rocky planets around UV-bright WDs.…

IVOA Registry (Virtual Observatory)2025 · Astronomical catalogue

…Ultraviolet flare emission can drive photochemistry in exoplanet atmospheres and even serve as the primary source of uncertainty in atmospheric retrievals.… …We present new near-UV (NUV) and optical observations of flares from three M dwarfs obtained at 20s cadence with Swift and the Transiting Exoplanet Survey Satellite (TESS), along with…

IVOA Registry (Virtual Observatory)2022 · Astronomical catalogue

…The absorption signal repeats during a partial transit obtained a month later, but is marginally stronger and bluer, perhaps reflecting changes in the stellar wind environment.… …We find that our models generally overpredict the measured magnitude of the absorption during transit, the size of the blueshift, or both.…

IVOA Registry (Virtual Observatory)2022 · Astronomical catalogue

…Using Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph, we measure a transit depth of 11.1{+/-}1.5% in the blue wing and 8{+/-}3% in the red.… …This signal is unlikely to be due to stellar variability, but should be confirmed by an upcoming second transit observation with HST.…

IVOA Registry (Virtual Observatory)2021 · Astronomical catalogue

…Neptune-size exoplanets seem particularly sensitive to atmospheric evaporation, making it essential to characterize the stellar high-energy radiation that drives this mechanism.… …Here we report on three additional transit observations from the Panchromatic Comparative Exoplanet Treasury program, obtained with the HST Cosmic Origin Spectrograph.…
