Exoplanets prediction in multiplanetary systems [PDF]
Publications of the Astronomical Society of Australia, 2021 AbstractWe present the results of a search for additional exoplanets in all multiplanetary systems discovered to date, employing a logarithmic spacing between planets in our Solar System known as the Titius–Bode (TB) relation. We use the Markov Chain Monte Carlo method and separately analyse 229 multiplanetary systems that house at least three or more ...

Sensitive Multibeam Targeted SETI Observations toward 33 Exoplanet Systems with FAST [PDF]
Astronomical Journal, 2022 As a major approach to looking for life beyond the Earth, the search for extraterrestrial intelligence (SETI) is committed to searching for technosignatures such as engineered radio signals that are indicative of technologically capable life.

The Mass Budgets and Spatial Scales of Exoplanet Systems and Protoplanetary Disks [PDF]
Astrophysical Journal, 2021 Planets are born from disks of gas and dust, and observations of protoplanetary disks are used to constrain the initial conditions of planet formation.

Speckle Imaging Characterization of Radial Velocity Exoplanet Systems [PDF]
Astronomical Journal, 2020 We conducted speckle imaging observations of 53 stellar systems that were members of long-term radial velocity (RV) monitoring campaigns and exhibited substantial accelerations indicative of planetary or stellar companions in wide orbits.

The Astronomical Journal, 2023 We investigate and compare the composition of M-dwarf planets in systems with only one known planet (“singles”) to those residing in multiplanet systems (“multis”) and the fundamental properties of their host stars.

Analysis of the exoplanet containing system Kepler-91 [PDF]
Astrophysics and Space Science, 2015 We have applied the graphical user interfaced close binary system analysis program WinFitter to an intensive study of Kepler 91 using all the available photometry from the NASA Exoplanet Archive (NEA) at the Caltech website: http://exoplanetarchive.ipac.caltech.edu . Our fitting function for the tidal distortion derives from the relevant Radau equation

Kepler-80 Revisited: Assessing the Participation of a Newly Discovered Planet in the Resonant Chain
The Astronomical Journal, 2023 In this paper, we consider the chain of resonances in the Kepler-80 system and evaluate the impact that the additional member of the resonant chain discovered by Shallue & Vanderburg has on the dynamics of the system and the physical parameters that can ...
