Digital color codes of stars
Jan-Vincent Harre, René Heller
Publications in astrophysics are nowadays mainly published and read in digitized formats. Astrophysical publications in both research and in popular outreach often use colorful rep…
Analysis of the X-ray spectrum of the hot bubble of BD+30°3639
Detlef Schönberner, Ralf Jacob, René Heller +1
We developed a model for wind-blown bubbles with temperature and density profiles based on self-similar solutions including thermal conduction. We constructed also heat-conduction…
Luminosity Discrepancy in the Equal-Mass, Pre--Main Sequence Eclipsing Binary Par 1802: Non-Coevality or Tidal Heating?
Y. Gómez Maqueo Chew, K. G. Stassun, A. Prša +5
Parenago 1802, a member of the ~1 Myr Orion Nebula Cluster, is a double-lined, detached eclipsing binary in a 4.674 d orbit, with equal-mass components (M_2/M_1 = 0.985 \pm 0.029).…
The SDSS White Dwarf - M Star Library
René Heller, Axel D. Schwope, Roy H. Østensen
The Sloan Digital Sky Survey (SDSS), originally targeted at quasi-stellar objects, has provided us with a wealth of astronomical byproducts through the last decade. Since then, the…
Tidal effects on brown dwarfs: Application to the eclipsing binary 2MASSJ05352184-0546085 - The anomalous temperature reversal in the context of tidal heating
René Heller, Brian Jackson, Rory Barnes +2
2MASSJ05352184-0546085 (2M0535-05) is the only known eclipsing brown dwarf (BD) binary, and so may serve as an important benchmark for models of BD formation and evolution. However…
