Constraints on the Equation-of-State of neutron stars from nearby neutron star observations
R. Neuhäuser, V. V. Hambaryan, M. M. Hohle +1
We try to constrain the Equation-of-State (EoS) of supra-nuclear-density matter in neutron stars (NSs) by observations of nearby NSs. There are seven thermally emitting NSs known f…
On identifying the neutron star that was born in the supernova that placed 60Fe onto the Earth
R. Neuhäuser, N. Tetzlaff, T. Eisenbeiss +1
Recently, 60Fe was found in the Earth crust formed in a nearby recent supernova (SN). If the distance to the SN and mass of the progenitor of that SN was known, then one could cons…
Constraints on neutron-star theories from nearby neutron star observations
Ralph Neuhäuser, Valeri V. Hambaryan, Nina Tetzlaff +2
We try to constrain the nuclear Equation-of-State (EoS) and supernova ejecta models by observations of young neutron stars in our galactic neighbourhood. There are seven thermally…
Spectral classification of Pleiades brown dwarf candidates
M. Seeliger, R. Neuhäuser, T. Eisenbeiss
We report on the results of the spectroscopy of 10 objects previously classified as brown dwarf candidates via RIJHK colors by Eisenbeiss et al. (2009), who performed deep imaging…
A new flare star member candidate in the Pleiades cluster
M. Moualla, T. O. B. Schmidt, R. Neuhäuser +19
We present a new flare star, which was discovered during our survey on a selected field at the edge of the Pleiades cluster. The field was observed in the period 2007 - 2010 with t…
The origin of RXJ1856.5-3754 and RXJ0720.4-3125 -- updated using new parallax measurements
Nina Tetzlaff, Thomas Eisenbeiss, Ralph Neuhaeuser +1
RXJ1856 and RXJ0720 are the only young isolated radio-quiet neutron stars (NSs) for which trigonometric parallaxes were measured. Due to detection of their thermal emission in X-ra…
