Detection of faculae in the transit and transmission spectrum of WASP-69b
D. J. M. Petit dit de la Roche, H. Chakraborty, M. Lendl +9
Context: Transmission spectroscopy is a powerful tool for understanding exoplanet atmospheres. At optical wavelengths, it makes it possible to infer the composition and the presenc…
JWST reveals a rapid and strong day side variability of 55 Cancri e
J. A. Patel, A. Brandeker, D. Kitzmann +16
The nature of the close-in rocky planet 55 Cnc e is puzzling despite having been observed extensively. Its optical and infrared occultation depths show temporal variability, in add…
SAGE: A tool to constrain impacts of stellar activity on transmission spectroscopy
Hritam Chakraborty, Monika Lendl, Babatunde Akinsanmi +2
Transmission spectroscopy is a proven technique to study a transiting exoplanet's atmosphere. However, stellar surface inhomogeneities, spots and faculae, alter the observed transm…
Why every observatory needs a disco ball
Robert J. Cumming, Alexander G. M. Pietrow, Livia Pietrow +5
Commercial disco balls provide a safe, effective and instructive way of observing the Sun. We explore the optics of solar projections with disco balls, and find that while sunspot…
Spatially resolving polycyclic aromatic hydrocarbons in Herbig Ae disks with VISIR-NEAR at the VLT
Gideon Yoffe, Roy van Boekel, Aigen Li +15
We use the long-slit spectroscopy mode of the VISIR-NEAR experiment to perform diffraction-limited observations of eight nearby Herbig Ae protoplanetary disks. We extract spectra f…
Center-to-limb variation of spectral lines and continua observed with SST/CRISP and SST/CHROMIS
A. G. M. Pietrow, D. Kiselman, O. Andriienko +3
Observations of center-to-limb variations (CLV) of spectral lines and continua provide a good test for the accuracy of models of solar and stellar atmospheric structure and spectra…
Early Release Science of the exoplanet WASP-39b with JWST NIRISS
Adina D. Feinstein, Michael Radica, Luis Welbanks +86
Transmission spectroscopy provides insight into the atmospheric properties and consequently the formation history, physics, and chemistry of transiting exoplanets. However, obtaini…
Early Release Science of the exoplanet WASP-39b with JWST NIRSpec PRISM
Z. Rustamkulov, D. K. Sing, S. Mukherjee +91
Transmission spectroscopy of exoplanets has revealed signatures of water vapor, aerosols, and alkali metals in a few dozen exoplanet atmospheres. However, these previous inferences…
First detection of a disk free of volatile elements around a young A-type star: A sign of collisions between rocky planets?
M. E. van den Ancker, N. P. Gentile Fusillo, T. J. Haworth +7
Aims. We present the first detailed analysis of the astrophysical parameters of the poorly studied Sco-Cen member HD 152384 and its circumstellar environment. Methods. We analyze n…
New constraints on the HR 8799 planetary system from mid-infrared direct imaging
D. J. M. Petit dit de la Roche, M. E. van den Ancker, M. Kissler-Patig +2
Direct imaging is a tried and tested method of detecting exoplanets in the near infrared, but has so far not been extended to longer wavelengths. New data at mid-IR wavelengths (8-…
