Newton’s Law of Universal Gravitation

- Ø. Grøn
- Physics, Geology
- 2009

Newton's Law of Universal Gravitation The formula Fg = mg is used to describe the weight of an object, in Newtons. Looking at the formula more closely, we see: • The term ‘weight’ is also known as… Expand

Warm Inflation

- Ø. Grøn
- Physics
- 2016

Abstract: I show here that there are some interesting differences between the predictions of warm and cold inflation models focusing in particular upon the scalar spectral index ns and the… Expand

The significance of the Schott energy for energy-momentum conservation of a radiating charge obeying the Lorentz–Abraham–Dirac equation

- Ø. Grøn
- Physics
- 2011

It is shown that energy and momentum are conserved during the runaway motion of a radiating charge and during free fall of a charge in a gravitational field. The runaway motion demonstrates the… Expand

The North Atlantic Oscillations: Cycle Times for the NAO, the AMO and the AMOC

- K. L. Seip, Ø. Grøn, Hui Wang

- 19 March 2019

We show that oceanic cycle lengths persist across oceanic cyclic time-series by comparing cycles in series that come from “sister” measurements in the North Atlantic Ocean. These are the North… Expand

General static plane-symmetric solutions of the Einstein-Maxwell equations

- P. A. Amundsen, Ø. Grøn
- Physics
- 15 April 1983

A general form of the metric in a space-time with nonvanishing cosmological constant outside a massive, electrically charged plane of infinite extension is found as a solution of the Einstein-Maxwell… Expand

A charged generalization of Florides' interior Schwarzschild solution

- Ø. Grøn
- Physics
- 1 June 1986

The new class of interior Schwarzschild solutions found by Florides is generalized to the charged case. A particular solution within this class is found, which represents an electromagnetic… Expand

Viscous inflationary universe models

- Ø. Grøn
- Physics
- 1 November 1990

The research on viscous cosmological models is reviewed and carried further. Inflationary cosmological models of Bianchi type-I with shear, bulk, and nonlinear viscosity are studied. The inflation… Expand

Universe models with negative bulk viscosity

The concept of negative temperatures has occasionally been used in connection with quantum systems. A recent example of this sort is reported in the paper of S. Braun et al. (Science 339:52, 2013),… Expand

On the statistical nature of distinct cycles in global warming variables

- K. L. Seip, Ø. Grøn
- Environmental ScienceClimate Dynamics
- 1 June 2019

Cycle times found in many oceanic time series have been explained with references to external mechanisms that act on the systems. Here we show that when we extract cycle times from 100 sets of paired… Expand
