SOPHIE and TESS characterization of fourteen TESS Objects of Interest: nine planetary systems and five low-mass stellar companions
N. Heidari, G. Hébrard, S. Sousa +61
We present fourteen TESS Objects of Interest (TOIs) from the SOPHIE-TESS follow-up program. Combining TESS photometry, SOPHIE radial velocities (RVs), ground-based photometry, and…
The Occurrence Rate of Nearby Planetary Companions to Hot Jupiters
Lizhou Sha, Andrew M. Vanderburg, Chelsea X. Huang +33
Of the > 500 confirmed transiting hot jupiters and approximately 2000 additional candidates today, only ten are known to have nearby companion planets. The survival of nearby compa…
ExoClock Project IV: A homogeneous catalogue of 620 updated exoplanet ephemerides
A. Kokori, A. Tsiaras, G. Pantelidou +323
The ExoClock project is an open platform aiming to monitor exoplanets by integrating observations from space and ground based telescopes. This study presents an updated catalogue o…
Characterization of the Visual Binary TOI-6883AB and its dynamical implications for the planetary companion TOI-6883Ab
G. Conzo, F. Campos, F. Conti +1
We demonstrate that TOI-6883 is a physically bound visual binary system composed of two solar-type stars, TOI-6883A (TIC 393818343) and TOI-6883B (TIC 393818340), initially regarde…
The Eccentricity Distribution of Warm Sub-Saturns in TESS
Tyler R. Fairnington, Jiayin Dong, Chelsea X. Huang +45
We present the eccentricity distribution of warm sub-Saturns (4-8 Re, 8-200 day periods) as derived from an analysis of transit light curves from NASA's Transiting Exoplanet Survey…
TIC 393818343 c: Discovery and characterization of a Neptune-like planet in the Delphinus constellation
G. Conzo, N. Leiner, K. Lynch +3
We report on the statistical confirmation of a second planet inside the TIC 393818343 system. The first planet TIC 393818343 b has been confirmed and classified as a Warm Jupiter p…
Planet Hunters NGTS: New Planet Candidates from a Citizen Science Search of the Next Generation Transit Survey Public Data
Sean M. O'Brien, Megan E. Schwamb, Samuel Gill +35
We present the results from the first two years of the Planet Hunters NGTS citizen science project, which searches for transiting planet candidates in data from the Next Generation…
Multiband Photometry Evolution in the First Weeks of SN 2023ixf, a possible II-L Subtype Supernova
Bianciardi G., Ciccarelli A. M., Conzo G. +8
Multiband photometric observations and their evaluation to instrumental magnitudes were performed using standard Johnson-Cousins filters (B, V, Rc) as well r and g Sloan filters, a…

G. Conzo, M. Moriconi, I. Peretto
MaGiV-1 is a candidate triple ellipsoidal star system in Vulpecula at coordinates RA(J2000) 19:52:19.13 DEC(J2000) +23:29:59.7 classified as ELL+ELL, number 2344411 in AAVSO VSX da…
ExoClock Project III: 450 new exoplanet ephemerides from ground and space observations
A. Kokori, A. Tsiaras, B. Edwards +214
The ExoClock project has been created with the aim of increasing the efficiency of the Ariel mission. It will achieve this by continuously monitoring and updating the ephemerides o…
