Doppler Tomography as a tool for characterising exoplanet atmospheres II: an analysis of HD 179949 b

Autor: Matthews, S. M., Watson, C. A., de Mooij, E. J. W., Marsh, T. R., Brogi, M., Merritt, S. R., Smith, K. W., Steeghs, D.

High-resolution Doppler spectroscopy provides an avenue to study the atmosphere of both transiting and non-transiting planets. This powerful method has also yielded some of the most robust atmospheric detections to date. Currently, high-resolution Do

Photometric monitoring of Beta Pictoris in 1981 showed anomalous fluctuations of up to 4% over several days, consistent with foreground material transiting the stellar disk. The subsequent discovery of the gas giant planet Beta Pictoris b and the pre

Ground-Based Transmission Spectroscopy with FORS2: A featureless optical transmission spectrum and detection of H$_2$O for the ultra-hot Jupiter WASP-103b

Autor: Wilson, J., Gibson, N. P., Nikolov, N., Constantinou, S., Madhusudhan, N., Goyal, J., Barstow, J. K., Carter, A. L., de Mooij, E. J. W., Drummond, B., Mikal-Evans, T., Helling, C., Mayne, N. J., Sing, D. K.

We report ground-based transmission spectroscopy of the highly irradiated and ultra-short period hot-Jupiter WASP-103b covering the wavelength range $\approx$ 400-600 nm using the FORS2 instrument on the Very Large Telescope. The light curves show si

S., West, R. G., Wheatley, P. J.

We have discovered a new, near-equal mass, eclipsing M dwarf binary from the Next Generation Transit Survey. This system is only one of 3 field age ($>$ 1 Gyr), late M dwarf eclipsing binaries known, and has a period of 1.74774 days, similar to that
