Multiple planetary systems: Properties of the current sample
(Elsevier Science, 2017-08)
We carry out analyses on stellar and planetary properties of multiple exoplanetary systems in the currently available sample. With regards to the stars, we study their temperature, distance from the Sun, and metallicity ...
Investigation of the inner structures around HD169142 with VLT/SPHERE
(Oxford University Press, 2018)
We present observations of the Herbig Ae star HD 169142 with the VLT/SPHERE instruments InfraRed Dual-band Imager and Spectrograph (IRDIS) (K1K2 and H2H3 bands) and the Integral Field Spectrograph (IFS) (Y, J and H bands). ...
ALMA observations of the nearby AGB star L-2 Puppis I. Mass of the central star and detection of a candidate planet
(EDP Sciences, 2016)
Six billion years from now, while evolving on the asymptotic giant branch (AGB), the Sun will metamorphose from a red giant into a beautiful planetary nebula. This spectacular evolution will impact the solar system planets, ...
Collisions, Cosmic Radiation and the Colors of the Trojan Asteroids
(Academic Press Inc Elsevier Science, 2009-04)
The Trojan asteroids orbit about the Lagrangian points of Jupiter and the
residence times about their present location are very long for most of them.
If these bodies originated in the outer Solar System, they should be ...
The next generation transit survey (NGTS)
(Oxford University Press, 2018)
We describe the Next Generation Transit Survey (NGTS), which is a ground-based project searching for transiting exoplanets orbiting bright stars. NGTS builds on the legacy of previous surveys, most notably WASP, and is ...
How Jupiters Save or Destroy Inner Neptunes around Evolved Stars
(IOP Publishing, 2020-07)
In about 6 Gyr our Sun will evolve into a red giant and finally end its life as a white dwarf. This stellar metamorphosis will occur to virtually all known host stars of exoplanetary systems and is therefore crucial for ...
Precision radial velocities of 15 M5–M9 dwarfs
(Royal Astronomical Society, 2014-02-20)
We present radial velocity measurements of a sample of M5V–M9V stars from our Red-Optical
Planet Survey, operating at 0.652–1.025 µm. Radial velocities for 15 stars, with rms precision
down to 2.5 m s−1 over a week-long ...
