Comparison of Rutherford's atomic model with the Standard Model of particle physics and other models

Journal of the Royal Society of New Zealand, Volume 51, Issue 3-4, Page 538-556, September ‐ December 2021., 2021
ABSTRACT Ernest Rutherford is known almost universally as the discoverer of the structure of the atom. He is less well known for his discovery of the proton. Even less well known is a set of hypotheses on the structure of matter that was proposed by Newton 300 years ago.

The Fundamental Connections between the Solar System and Exoplanetary Science

Journal of Geophysical Research: Planets, Volume 126, Issue 2, February 2021., 2021
Abstract Over the past several decades, thousands of planets have been discovered outside our Solar System. These planets exhibit enormous diversity, and their large numbers provide a statistical opportunity to place our Solar System within the broader context of planetary structure, atmospheres, architectures, formation, and evolution.

OGLE-2019-BLG-1180Lb: Discovery of a Wide-orbit Jupiter-mass Planet around a Late-type Star

The Astronomical Journal, 2023
We report on the discovery and analysis of the planetary microlensing event OGLE-2019-BLG-1180 with a planet-to-star mass ratio q ∼ 0.003. The event OGLE-2019-BLG-1180 has unambiguous cusp-passing and caustic-crossing anomalies, which were caused by a ...

Detecting Multiplanetary Systems with Gravitational Microlensing and the Roman Space Telescope

The Astronomical Journal, 2023
It is plausible that most of the Stars in the Milky Way Galaxy, like the Sun, consist of planetary systems, instead of a single planet. Out of the estimately discovered 3980 planet-hosting stars, about 860 of them are known to be multiplanetary systems ...

Possibility of Detection of Exomoons with Inclined Orbits Orbiting Pulsar Planets Using the Time‐of‐Arrival Analysis

Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014
The perturbation caused by planet‐moon binarity on the time‐of‐arrival (TOA) signal of a pulsar with an orbiting planet is derived for the case of the orbit of the planet‐moon system inclined of an angle α with respect to the plane of the orbit of the planet‐moon barycenter around the pulsar.
