Low-mass companions to nine stars

Andrzej Niedzielski, Robert Jaros, Divyansh Srivastava +5

We present an independent spectroscopic and radial velocity analysis for nine stars from the Pennsylvania-Toruń Planet Search. For BD+24 4697, we present an updated true companion'…

Search for planets in hot Jupiter systems with multi-sector TESS photometry. III. A study of ten systems enhanced with new ground-based photometry

G. Maciejewski, M. Fernández, A. Sota +12

The loneliness of hot Jupiters supports the high-eccentricity migration as a primary path leading to the formation of systems with those planets stripped of any close-in planetary…

A hot super-Earth planet in the WASP-84 planetary system

G. Maciejewski, J. Golonka, W. Łoboda +3

Hot Jupiters have been perceived as loners devoid of planetary companions in close orbital proximity. However, recent discoveries based on space-borne precise photometry have revea…

Planet-star interactions with precise transit timing. III. Entering the regime of dynamical tides

G. Maciejewski, M. Fernandez, A. Sota +14

Hot Jupiters on extremely short-period orbits are expected to be unstable to tidal dissipation and spiral toward their host stars. That is because they transfer the angular momentu…

Photodynamical analysis of the nearly resonant planetary system WASP-148: Accurate transit-timing variations and mutual orbital inclination

J. M. Almenara, G. Hébrard, R. F. Díaz +23

WASP-148 is a recently announced extra-solar system harbouring at least two giant planets. The inner planet transits its host star. The planets travel on eccentric orbits and are n…

Search for planets in hot Jupiter systems with multi-sector TESS photometry. II. Constraints on planetary companions in 12 systems

G. Maciejewski

Uninterrupted observations from space-borne telescopes provide the photometric precision that is required to detect shallow transits of small planets missed by ground-based surveys…
