Why might they be giants? Towards an understanding of polar gigantism.

Healthcare and Compassion: Towards an Awareness of Intersubjective Vulnerability; Comment on “Why and How Is Compassion Necessary to Provide Good Quality Healthcare?”

How to instill compassion in a healthcare organization? In this article, I respond to Marianna Fotaki’s proposals in her piece, ‘Why and how is compassion necessary to provide good quality healthcare?’ by drawing on insights from organization studies. Following Fotaki, I argue that to instill targets and formal measures for assessing compassion would be problematic. I conclude by drawing on psy...

We consider the origin of the so–called S stars orbiting the supermassive black hole at the very center of the Galaxy. These are usually assumed to be massive main–sequence stars. We argue instead that they are the remnants of low–to– intermediate mass red giants which have been scattered on to near–radial orbits and tidally stripped as they approach the central black hole. Such stars retain on...

Why polar gigantism and Palaeozoic gigantism are not equivalent: effects of oxygen and temperature on the body size of ectotherms

Using Hipparcos parallaxes, we show that the metallic A-F giants found by Hauck (1986) on the basis of their high ∆m2 index in Geneva photom-etry are on average more evolved than their non-metallic counterparts. Their mass distribution, rate of binaries and v sin i are shown to be incompatible with those of Am stars, so that they cannot be descendants of the latter. They might be former normal ...

ISOGAL survey of Baade’s Windows

The Baade’s Windows of low obscuration towards the inner parts of the Galactic bulge represent ideal places in which to develop an understanding of the ISOGAL colour-magnitude diagrams. Unlike the case for the solar neighbourhood, their contents are at a uniform distance from the Sun, affected only by the finite thickness of the Bulge. The objects detected in the ISOGAL survey are found to be l...
