Neutron Stars and the High Density Equation of State (2009)
Klahn, T., Roberts, C. D., Blaschke, D. B., Sandin, F.
One of the key ingredients to understand the properties of neutrons stars is the equation of state at finite densities far beyond nuclear saturation. Investigating the phase structure of quark matter...

1. Climate change in the subarctic is expected to influence vegetation composition, specifically bryophyte and lichen communities, thereby modifying litter decomposition rates and carbon (C) dynamics...
Survey of nucleon electromagnetic form factors (2008)
Cloet, I. C., Eichmann, G., El-Bennich, B., Klahn, T., Roberts, C. D.
A dressed-quark core contribution to nucleon electromagnetic form factors is calculated. It is defined by the solution of a Poincare' covariant Faddeev equation in which dressed-quarks provide the...
Sequential deconfinement of quark flavors in neutron stars (2008)
Blaschke, D., Sandin, F., Klahn, T., Berdermann, J.
We suggest a scenario where the three light quark flavors are sequentially deconfined under increasing pressure in cold asymmetric nuclear matter as found, e.g., in neutron stars. The basis for our...

Color superconducting quark matter in compact stars (2007)
Blaschke, D. B., Klahn, T., Sandin, F.
Recent indications for high neutron star masses (M \sim 2 M_sun) and large radii (R > 12 km) could rule out soft equations of state and have provoked a debate whether the occurence of quark matter in...
Equation of state at high densities and modern compact star observations (2007)
Blaschke, D., Klahn, T., Sandin, F.
Recently, observations of compact stars have provided new data of high accuracy which put strong constraints on the high-density behaviour of the equation of state of strongly interacting matter...
Equation of state for hybrid compact stars with a nonlocal chiral quark model (2007)
Grunfeld, A. G., Berdermann, J., Blaschke, D. B., Klahn, T., Dumm, D. Gomez, Scoccola, N. N.
We study the thermodynamics of two flavor color superconducting (2SC) quark matter within a nonlocal chiral quark model, using both instantaneous and covariant nonlocal interactions. For applications...
Hybrid stars within a covariant, nonlocal chiral quark model (2007)
Blaschke, D. B., Dumm, D. Gomez, Grunfeld, A. G., Klahn, T., Scoccola, N. N.
We present a hybrid equation of state (EoS) for dense matter in which a nuclear matter phase is described within the Dirac-Brueckner-Hartree-Fock (DBHF) approach and a two-flavor quark matter phase...
Ferstl, W., Klahn, T., Schweikert, W., Billeb, G., Schwarzer, M., Löbbecke, S.
A procedure is described for successfully benchmarking different inline spectroscopic techniques in a microreaction plant. The objective was to identify the highest calibration precision for the...
Phase diagram of neutron star quark matter in nonlocal chiral models (2006)
Dumm, D. Gomez, Blaschke, D. B., Grunfeld, A. G., Klahn, T., Scoccola, N. N.
We analyze the phase diagram of two-flavor quark matter under neutron star constraints for a nonlocal covariant quark model within the mean field approximation. Applications to cold compact stars are...
Modern compact star observations and the quark matter EoS (2006)
A hybrid equation of state for dense matter is presented that satisfies phenomenological constraints from modern compact star observations which indicate high maximum masses of about 2 M_sun and...
Compact star constraints on the high-density EoS (2006)
Grigorian, H., Blaschke, D., Klahn, T.
A new scheme for testing the nuclear matter (NM) equation of state (EoS) at high densities using constraints from compact star (CS) phenomenology is applied to neutron stars with a core of deconfined...

We present a hybrid equation of state (EoS) for dense matter that satisfies phenomenological constraints from modern compact star (CS) observations which indicate high maximum masses (M = 2 M_sun)...
Klahn, T., Blaschke, D., Typel, S., Faessler, A., Fuchs, C., ...
A new scheme for testing nuclear matter equations of state (EsoS) at high densities using constraints from neutron star phenomenology and a flow data analysis of heavy-ion collisions is suggested. An...
