High-resolution Emission Spectroscopy of the Ultrahot Jupiter KELT-9b: Little Variation in Day- and Nightside Emission Line Contrasts

Andrew Ridden-Harper, Ernst de Mooij, Ray Jayawardhana +3

The transmission spectrum of the ultrahot Jupiter KELT-9b ( 4000 K) exhibits absorption by several metal species. We searched for atomic and molecular lines in its e…

Astrophotonic Solutions for Spectral Cross-Correlation Techniques

Suresh Sivanandam, Ross Cheriton, Polina Zavyalova +7

Using photonic devices, we developed a new approach to traditional spectroscopy where the spectral cross-correlation with a template spectrum can be done entirely on-device. By cre…

Transmission spectroscopy with VLT FORS2: a featureless spectrum for the low-density transiting exoplanet WASP-88b

Petros Spyratos, Nikolay Nikolov, John Southworth +10

We present ground-based optical transmission spectroscopy of the low-density hot Jupiter WASP-88b covering the wavelength range 4413-8333 Å with the FORS2 spectrograph on the Very…

Is TiO emission present in the ultra-hot Jupiter WASP-33b? A reassessment using the improved ExoMol Toto line list

Dilovan B. Serindag, Stevanus K. Nugroho, Paul Mollière +3

[abridged] Efficient absorption of stellar UV and visible radiation by TiO and VO is predicted to drive temperature inversions in the upper atmospheres of hot Jupiters. However, fe…

Arid or Cloudy: Characterizing the Atmosphere of the super-Earth 55 Cancri e using High-Resolution Spectroscopy

Abhinav Jindal, Ernst J. W. de Mooij, Ray Jayawardhana +6

The nearby super-Earth 55 Cnc e orbits a bright (V = 5.95 mag) star with a period of ~ 18 hours and a mass of ~ 8 Earth masses. Its atmosphere may be water-rich and have a large sc…

Search for TiO and Optical Night-side Emission from the Exoplanet WASP-33b

Miranda K. Herman, Ernst J. W. de Mooij, Ray Jayawardhana +1

With a temperature akin to an M-dwarf, WASP-33b is among the hottest Jupiters known, making it an ideal target for high-resolution optical spectroscopy. By analyzing both transmiss…
