Detection of Nitrogen gas in the Pictoris circumstellar disk
P. A. Wilson, R. Kerr, A. Lecavelier des Etangs +4
The debris disk surrounding Pictoris has a gas composition rich in carbon and oxygen, relative to solar abundances. Two possible scenarios have been proposed to explain this en…
Detecting isotopologues in exoplanet atmospheres using ground-based high-dispersion spectroscopy
P. Mollière, I. A. G. Snellen
Cross-correlation is a well-tested method for exoplanet characterization. A new, potentially powerful application is the measurement of atmospheric isotope ratios. In particular D/…
Molecule mapping of HR8799b using OSIRIS on Keck: Strong detection of water and carbon monoxide, but no methane
D. J. M. Petit dit de la Roche, H. J. Hoeijmakers, I. A. G. Snellen
Context. In 2015, Barman et al. (ApJ, 804, 61) presented detections of absorption from water, carbon monoxide, and methane in the atmosphere of the directly imaged exoplanet HR8799…
Studying bright variable stars with the Multi-site All-Sky CAmeRA (MASCARA)
O. Burggraaff, G. J. J. Talens, J. Spronck +6
The Multi-site All-Sky CAmeRA (MASCARA) aims to find the brightest transiting planet systems by monitoring the full sky at magnitudes , taking data every 6.4 seconds. The…
Na I and H absorption features in the atmosphere of MASCARA-2b/KELT-20b
N. Casasayas-Barris, E. Palle, F. Yan +9
We have used the HARPS-North high resolution spectrograph (=115 000) at TNG to observe one transit of the highly irradiated planet MASCARA-2b/KELT-20b. Using only one…
