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

Zieba, Sebastian Zwintz, Konstanze Kenworthy, Matthew

The β 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 transiting exocomets. The inner planet, β Pictoris c, has also been indirectly detected with radial velocity (RV) measurements. The star is a known δ Scuti pulsator,...

HD 28109 hosts a trio of transiting Neptunian planets including a near-resonant pair, confirmed by ASTEP from Antarctica

Dransfield, Georgina Triaud, Amaury Guillot, Tristan

We report on the discovery and characterisation of three planets orbiting the F8 star HD 28109, which sits comfortably in TESS's continuous viewing zone. The two outer planets have periods of 56.0067 ± 0.0003 days and 84.2597 +0.0010-0.0008 days, which implies a period ratio very close to that of the first-order 3:2 mean motion resonance,...
