Investigating the eccentricity distribution of transiting, long-period giant planets
Ahlam Alqasim, Teruyuki Hirano, Yasunori Hori +12
Eccentric giant planets are predicted to have acquired their eccentricity through two major mechanisms: the Kozai-Lidov effect or planet-planet scattering, but it is normally diffi…
TOI-757 b: an eccentric transiting mini-Neptune on a 17.5-d orbit
A. Alqasim, N. Grieves, N. M. Rosário +129
We report the spectroscopic confirmation and fundamental properties of TOI-757 b, a mini-Neptune on a 17.5-day orbit transiting a bright star ( mag) discovered by the TESS…
A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067
R. Luque, H. P. Osborn, A. Leleu +149
Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…
TOI-544 b: a potential water-world inside the radius valley in a two-planet system
H. L. M. Osborne, V. Van Eylen, E. Goffo +32
We report on the precise radial velocity follow-up of TOI-544 (HD 290498), a bright K star (V=10.8), which hosts a small transiting planet recently discovered by the Transiting Exo…
TOI-1130: A photodynamical analysis of a hot Jupiter in resonance with an inner low-mass planet
J. Korth, D. Gandolfi, J. Šubjak +59
The TOI-1130 is a known planetary system around a K-dwarf consisting of a gas giant planet, TOI-1130 c, on an 8.4-day orbit, accompanied by an inner Neptune-sized planet, TOI-1130…
TOI-733 b: a planet in the small-planet radius valley orbiting a Sun-like star
Iskra Y. Georgieva, Carina M. Persson, Elisa Goffo +40
We report the discovery of a hot ( 1055 K) planet in the small planet radius valley transiting the Sun-like star TOI-733, as part of the KESPRINT follow-up pr…
A New Method to Determine X-ray Luminosity Functions of AGN and their Evolution with Redshift
Ahlam Alqasim, Mat J. Page
Almost all massive galaxies today are understood to contain supermassive black holes (SMBH) at their centers. SMBHs grew by accreting material from their surroundings, emitting X-r…
HD 20329b: An ultra-short-period planet around a solar-type star found by TESS
F. Murgas, G. Nowak, T. Masseron +45
We used TESS light curves and HARPS-N spectrograph radial velocity measurements to establish the physical properties of the transiting exoplanet candidate found around the star HD…
HD 191939 revisited: New and refined planet mass determinations, and a new planet in the habitable zone
J. Orell-Miquel, G. Nowak, F. Murgas +20
HD 191939 (TOI-1339) is a nearby (d=54pc), bright (V=9mag), and inactive Sun-like star (G9 V) known to host a multi-planet transiting system. Ground-based spectroscopic observation…
