Searching for substellar companion candidates with Gaia. II. A catalog of 9,698 planet candidate solar-type hosts

Flavien Kiefer, Anne-Marie Lagrange, Pascal Rubini +1

In a previous paper, we introduced a new tool called GaiaPMEX. It characterizes the mass and semi-major axis relative to the central star (sma) of a possible companion around any s…

Searching for substellar companion candidates with Gaia. I. Introducing the GaiaPMEX tool

Flavien Kiefer, Anne-Marie Lagrange, Pascal Rubini +1

The Gaia mission is expected to yield the detection of several thousands of exoplanets, perhaps at least doubling the number of known exoplanets. Although the harvest is expected t…

The Pictoris b Hill sphere transit campaign. Paper II: Searching for the signatures of the Pictoris exoplanets through time delay analysis of the Scuti pulsations

Sebastian Zieba, Konstanze Zwintz, Matthew Kenworthy +34

The Pictoris system is the closest known stellar system with directly detected gas giant planets, an edge-on circumstellar disc, and evidence of falling sublimating bodies and…

SPHERE RefPlanets: Search for epsilon Eridani b and warm dust

C. Tschudi, H. M. Schmid, M. Nowak +35

We carried out very deep VLT/SPHERE imaging polarimetry of the nearby system Eps Eri based on 38.5 hours of integration time with a 600 - 900 nm broadband filter to search for pola…

Dynamics of the Beta Pictoris planetary system and its falling evaporating bodies

H. Beust, J. Milli, A. Morbidelli +5

For decades, the spectral variations of Beta Pictoris have been modelled as the result of the evaporation of exocomets close to the star, termed falling evaporating bodies (FEBs).…
