Design of the Life Signature Detection Polarimeter LSDpol
Christoph U. Keller, Frans Snik, C. H. Lucas Patty +11
Many biologically produced chiral molecules such as amino acids and sugars show a preference for left or right handedness (homochirality). Light reflected by biological materials s…
Using all-sky optical observations for automated orbit determination and prediction for satellites in Low Earth Orbit
T. P. G. Wijnen, R. Stuik, M. Rodenhuis +2
We have used an existing, robotic, multi-lens, all-sky camera system, coupled to a dedicated data reduction pipeline, to automatically determine orbital parameters of satellites in…
The consequences of a nearby supernova on the early Solar System
Simon Portegies Zwart, Inti Pelupessy, Arjen van Elteren +2
If the Sun was born in a relatively compact open cluster, it is quite likely that a massive (10MSun) star was nearby when it exploded in a supernova. The repercussions of a superno…
Changes in orientation and shape of protoplanetary discs moving through an ambient medium
T. P. G. Wijnen, F. I. Pelupessy, O. R. Pols +1
Misalignments between the orbital planes of planets and the equatorial planes of their host stars have been observed in our solar system, in transiting exoplanets, and in the orbit…
Disc truncation in embedded star clusters: Dynamical encounters versus face-on accretion
T. P. G. Wijnen, O. R. Pols, F. I. Pelupessy +1
Observations indicate that the dispersal of protoplanetary discs in star clusters occurs on time scales of about 5 Myr. Several processes are thought to be responsible for this dis…
Characterising face-on accretion onto and the subsequent contraction of protoplanetary discs
T. P. G. Wijnen, O. R. Pols, F. I. Pelupessy +1
Observations indicate that stars generally lose their protoplanetary discs on a timescale of about 5 Myr. Which mechanisms are responsible for the disc dissipation is still debated…
Face-on accretion onto a protoplanetary disc
T. P. G. Wijnen, O. R. Pols, F. I. Pelupessy +1
Globular clusters (GCs) are known to harbor multiple stellar populations. To explain these observations Bastian et al. suggested a scenario in which a second population is formed b…
Empirical consequential angular momentum loss can solve long standing problems of CV evolution
Matthias R. Schreiber, Monica Zorotovic, Thomas P. G. Wijnen
The observed orbital period distribution of cataclysmic variables (CVs), the space density derived from observations, and the observed orbital period minimum are known to disagree…
Three in one go: consequential angular momentum loss can solve major problems of CV evolution
Matthias R. Schreiber, Monica Zorotovic, Thomas P. G. Wijnen
The average white dwarf (WD) masses in cataclysmic variables (CVs) have been measured to significantly exceed those of single WDs, which is the opposite of what is theoretically ex…
White dwarf masses in cataclysmic variables
T. P. G. Wijnen, M. Zorotovic, M. R. Schreiber
The white dwarf (WD) mass distribution of cataclysmic variables (CVs) has recently been found to dramatically disagree with the predictions of the standard CV formation model. The…
