Constraining the Nature of the PDS 70 Protoplanets with VLTI/GRAVITY

J. J. Wang, A. Vigan, S. Lacour +101

We present K-band interferometric observations of the PDS 70 protoplanets along with their host star using VLTI/GRAVITY. We obtained K-band spectra and 100 μas precision astromet…

Direct confirmation of the radial-velocity planet β Pic c

M. Nowak, S. Lacour, A. -M. Lagrange +90

Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…

First direct detection of an exoplanet by optical interferometry; Astrometry and K-band spectroscopy of HR8799 e

S. Lacour, M. Nowak, J. Wang +85

To date, infrared interferometry at best achieved contrast ratios of a few times 10−4 on bright targets. GRAVITY, with its dual-field mode, is now capable of high contrast obs…
