4XMM~J182531.5144036: A new persistent Be/X-ray binary found within the \emph{XMM-Newton} serendipitous survey
A. B. Mason, A. J. Norton, J. S. Clark +2
We aim to investigate the nature of time-variable X-ray sources detected in the {\it XMM-Newton} serendipitous survey. The X-ray light curves of objects in the {\it XMM-Newton} ser…
Mid-Infrared Spectroscopy of Components in Chondrites: Search for Processed Materials in Young Solar Systems and Comets
A. Morlok, C. M. Lisse, A. B. Mason +2
We obtained mid-infrared spectra of chondrules, matrix, CAIs and bulk material from primitive type 1-4 chondrites in order to compare them with the dust material in young, forming…
Mid-infrared spectra of differentiated meteorites (achondrites): Comparison with astronomical observations of dust in protoplanetary and debris disks
A. Morlok, C. Koike, K. Tomeoka +4
Mid-infrared (5 micron to 25 micron) transmission/absorption spectra of differentiated meteorites (achondrites) were measured to permit comparison with astronomical observations of…
Dust from collisions: A way to probe the composition of exo-planets?
A. Morlok, A. B. Mason, M. Anand +3
In order to link infrared observations of dust formed during planet formation in debris disks to mid-infrared spectroscopic data of planetary materials from differentiated terrestr…
High Mass X-ray Binaries in the NIR : Orbital solutions of two highly obscured systems
A. B. Mason, A. J. Norton, J. S. Clark +2
The maximum mass of a neutron star (NS) is poorly defined. Theoretical attempts to define this mass have thus far been unsuccessful. Observational results currently provide the onl…
