A high-mass Planetary Nebula in a Galactic Open Cluster [PDF]

, 2019
Planetary Nebulae are the ionised ejected envelopes surrounding the remnant cores of dying stars. Theory predicts that main-sequence stars with one to about eight times the mass of our sun may eventually form planetary nebulae. Until now no example has been confirmed at the higher mass range.

Planet-vortex interaction:How a vortex can shepherd a planetary embryo [PDF]

, 2014
Context: Anticyclonic vortices are considered as a favourable places for trapping dust and forming planetary embryos. On the other hand, they are massive blobs that can interact gravitationally with the planets in the disc.

From Geophysics to Astrophysics Twice: Africa's Rift to Einstein's Gravity, Earth's Magnetosphere to Planetary Fields via Hyperspatial Faraday Rotation

, 2018
The paper in "Geophysical Research Letters" being commented on (Birhanu et al, 2016) first came to the author's attention while reading "Africa's Big Break". (Hall, 2018) The comment begins by comparing failure or continued growth of rifts to tempering of glass - glass is reheated then suddenly cooled, making it tough enough to hammer nails into wood ...

The Architectural Design Rules of Solar Systems based on the New Perspective

, 2009
On the basis of the Lunar Laser Ranging Data released by NASA on the Silver Jubilee Celebration of Man Landing on Moon on 21st July 1969-1994, theoretical formulation of Earth-Moon tidal interaction was carried out and Planetary Satellite Dynamics was ...

Intracluster Planetary Nebulae [PDF]

, 2006
I review the progress in research on intracluster planetary nebulae over the last five years. Hundreds more intracluster planetary nebulae have been detected in the nearby Virgo and Fornax galaxy clusters, searches of several galaxy groups have been made, and intracluster planetary candidates have been detected in the distant Coma cluster.

Archaeology, Epigraphy and Skyscape: Keys to Understanding Dadanite and Lihyanite Conception of Time

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Dadan, the capital of the kingdom of Dadan and, later on, of Lihyan, was an important trading hub and place of worship in North‐West Arabia during the first millennium BCE. Located in the AlUla valley (Saudi Arabia), with naturally available fresh water, fertile soil and relative ease of travel through it, people gathered there for trade ...

Planet Populations as a Function of Stellar Properties

, 2018
Exoplanets around different types of stars provide a window into the diverse environments in which planets form. This chapter describes the observed relations between exoplanet populations and stellar properties and how they connect to planet formation ...

Review of asteroid, meteor, and meteorite‐type links

Meteoritics &Planetary Science, EarlyView.
Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.

Shock‐heated graphite in three IAB iron meteorites—Implications on the formation of diamond

Meteoritics &Planetary Science, EarlyView.
Abstract Iron meteorites, originating from the deepest parts of their parent bodies and separated during major break‐up events, surprisingly rarely contain diamonds despite experiencing similar pressure–temperature conditions as diamond‐bearing ureilites. In this study, graphite from three non‐magmatic IAB iron meteorites Canyon Diablo, Campo del Cielo,
