Open Letter to the Pontiff and Vatican Cardinals on Pervasively Corrupt Earth, Planetary, and Astrophysical Science

open access: yesAdvances in Social Sciences Research Journal, 2023
Five hundred years ago the Roman Catholic Church wrongly opposed science. In my fifty years as a scientist, I have observed the Catholic Church reaching out to science, wholly unaware of widespread corruption and cartel-like behavior under guise of science, which leads, I allege, to the Vatican aiding and abetting activities that are not only anti ...

The Search for Other Planets and Life [PDF]

open access: yes, 2010
This Les Houches School offers students a wide ranging view of the field of exoplanets and the search for life beyond the solar system. Observational and theoretical opportunities abound in a new field of astronomy that will be growing for decades to ...

The formation of Jupiter by hybrid pebble-planetesimal accretion [PDF]

open access: yes, 2018
The standard model for giant planet formation is based on the accretion of solids by a growing planetary embryo, followed by rapid gas accretion once the planet exceeds a so-called critical mass.

Planet Populations as a Function of Stellar Properties

open access: yes, 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 ...

Volatiles and refratories in solar analogs: no terrestial planet connection

open access: yes, 2010
We have analysed very high-quality HARPS and UVES spectra of 95 solar analogs, 24 hosting planets and 71 without detected planets, to search for any possible signature of terrestial planets in the chemical abundances of volatile and refractory elements ...

In Situ Formation and Dynamical Evolution of Hot Jupiter Systems [PDF]

open access: yes, 2016
Hot Jupiters, giant extrasolar planets with orbital periods shorter than ~10 days, have long been thought to form at large radial distances, only to subsequently experience long-range inward migration. Here, we propose that in contrast with this picture,

Spectral features of Earth-like planets and their detectability at different orbital distances around F, G, and K-type stars

open access: yes, 2013
We investigate the spectral appearance of Earth-like exoplanets in the HZ of different main sequence stars at different orbital distances. We furthermore discuss for which of these scenarios biomarker absorption bands may be detected during primary or ...

A Multiple Scattering Polarized Radiative Transfer Model: Application to HD 189733b [PDF]

open access: yes, 2015
We present a multiple scattering vector radiative transfer model which produces disk integrated, full phase polarized light curves for reflected light from an exoplanetary atmosphere.

The Ability of Significant Tidal Stress to Initiate Plate Tectonics [PDF]

open access: yes, 2019
Plate tectonics is a geophysical process currently unique to Earth, has an important role in regulating the Earth's climate, and may be better understood by identifying rocky planets outside our solar system with tectonic activity.

Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.
