KEPLER BANHATTI AND MODIFIED KEPLER BANHATTI INDICES

open access: yesINTERNATIONAL JOURNAL OF MATHEMATICS AND COMPUTER RESEARCH
We introduce a novel vertex degree based topological index, called Kepler Banhatti index. Also we put forward the modified Kepler Banhatti index of a graph. We propose the Kepler Banhatti and modified Kepler Banhatti exponentials of a graph. In this study, we determine the newly defined the Kepler Banhatti indices and their corresponding exponentials ...

Galileo's ship and the relativity principle

open access: yesNoûs, EarlyView.
Abstract It is widely acknowledged that the Galilean Relativity Principle, according to which the laws of classical systems are the same in all inertial frames in relative motion, has played an important role in the development of modern physics. It is also commonly believed that this principle holds the key to answering why, for example, we do not ...

Bertrand’s theorem and the double copy of relativistic field theories

open access: yesJournal of High Energy Physics
Which relativistic field theories give rise to Kepler dynamics in the two-body problem? We consider a class of Hamiltonians that is the unique relativistic extension of the Kepler problem preserving its so(4) algebra, and have orbits related through time

Gravitational quantization of exoplanet orbits in HD 10180, Kepler-32, Kepler-33, Kepler-102, and Kepler-186

open access: yes, 2015
The so-called "global polytropic model" is applied to the numerical study of the exoplanet systems HD 10180, Kepler-32, Kepler-33, Kepler-102, and Kepler-186. We compare computed distances of planets from their host stars with corresponding observations and discuss some further orbit predictions made by the model.

Heavy‐duty conceptual engineering

open access: yesNoûs, EarlyView.
Abstract Conceptual engineering is the process of assessing and improving our conceptual repertoire. Some authors have claimed that introducing or revising concepts through conceptual engineering can go as far as expanding the realm of thinkable thoughts and thus enable us to form beliefs, hypotheses, wishes, or desires that we are currently unable to ...

Assessing Input Legitimacy of Occupational Pensions in Europe

open access: yesRegulation &Governance, EarlyView.
ABSTRACT As private asset‐based welfare like funded occupational pension schemes gain importance, legitimacy concerns arise due to financial market downturns and low investment returns. This paper assesses their input legitimacy by distinguishing between individual‐direct and collective‐representative input possibilities in decision‐making processes ...

Kepler main-sequence solar-like stars: surface rotation and magnetic-activity evolution

open access: yesFrontiers in Astronomy and Space Sciences
While the mission’s primary goal was focused on exoplanet detection and characterization, Kepler made and continues to make extraordinary advances in stellar physics. Stellar rotation and magnetic activity are no exceptions.

“M. Leibnits étoit un grand homme”: The role of argument from epistemic authority in Du Châtelet's dispute with Mairan

open access: yesThe Southern Journal of Philosophy, EarlyView.
Abstract In my article, I propose to analyze the Du Châtelet‐Mairan dispute from the perspective of the modern theory of argumentation, focusing on the study of arguments from authority. I study separately the opinions of Du Châtelet and Mairan on the correct use of the argument from authority (Is the opponent using the argument correctly?

Ages of “Singles” versus “Multis”: Predictions for Dynamical Sculpting over Gyr in the Kepler Sample

open access: yesThe Astronomical Journal
The sample of host stars with multiple transiting planets has illuminated the orbital architectures of exoplanetary systems. These architectures may be shaped mostly by formation conditions, be continually sculpted by ongoing dynamical processes, or both.
