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…
The masses of the neutron and donor star in the high mass X-ray binary IGR J18027-2016
A. B. Mason, A. J. Norton, J. S. Clark +2
We report near-infrared observations of the supergiant donor to the eclipsing high mass X-ray binary pulsar IGR J18027-2016. We aim to determine its spectral type and measure its r…
The evolution and masses of the neutron star and donor star in the high mass X-ray binary OAO 1657-415
A. B. Mason, J. S. Clark, A. J. Norton +5
We report near-infrared radial velocity measurements of the recently identified donor star in the high mass X-ray binary system OAO 1657-415 obtained in the H band using ISAAC on t…
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…
Preliminary determinations of the masses of the neutron star and mass donor in the High Mass X-ray Binary system EXO 1722-363
A. B. Mason, A. J. Norton, J. S. Clark +2
We intended to measure the radial velocity curve of the supergiant companion to the eclipsing high mass X-ray binary pulsar EXO1722-363 and hence determine the stellar masses of th…
Spectral classification of the mass donors in the high-mass X-ray binaries EXO 1722-363 and OAO 1657-415
A. B. Mason, J. S. Clark, A. J. Norton +2
We report near-infrared observations of the mass donors of the eclipsing high-mass X-ray binary (HMXB) systems EXO 1722-363 and OAO 1657-415 in order to derive their accurate spect…
