pyaneti II: A multidimensional Gaussian process approach to analysing spectroscopic time-series
Oscar Barragán, Suzanne Aigrain, Vinesh M. Rajpaul +1
The two most successful methods for exoplanet detection rely on the detection of planetary signals in photometric and radial velocity time-series. This depends on numerical techniq…
A HARPS-N mass for the elusive Kepler-37d: a case study in disentangling stellar activity and planetary signals
V. M. Rajpaul, L. A. Buchhave, G. Lacedelli +22
To date, only 18 exoplanets with radial velocity (RV) semi-amplitudes m/s have had their masses directly constrained. The biggest obstacle to RV detection of such exoplanets i…
Planet Hunters TESS III: two transiting planets around the bright G dwarf HD 152843
Nora L. Eisner, Belinda A. Nicholson, Oscar Barragán +37
We report on the discovery and validation of a two-planet system around a bright (V = 8.85 mag) early G dwarf (1.43 , 1.15 , TOI 2319) using data from NASA's…
The HARPS search for southern extra-solar planets XLV. Two Neptune mass planets orbiting HD 13808: a study of stellar activity modelling's impact on planet detection
E. Ahrer, D. Queloz, V. M. Rajpaul +11
We present a comprehensive analysis of 10 years of HARPS radial velocities of the K2V dwarf star HD 13808, which has previously been reported to host two unconfirmed planet candida…
