A new timestep criterion for N-body simulations
Dang Pham, Hanno Rein, David S. Spiegel
We derive a new criterion for estimating characteristic dynamical timescales in N-body simulations. The criterion uses the second, third, and fourth derivatives of particle positio…
On the Orbits of Low-mass Companions to White Dwarfs and the Fates of the Known Exoplanets
J. Nordhaus, D. S. Spiegel
The ultimate fates of binary companions to stars (including whether the companion survives and the final orbit of the binary) are of interest in light of an increasing number of re…
Precision Astrometry of the Exoplanet Host Candidate GD 66
J. Farihi, J. P. Subasavage, E. P. Nelan +4
The potential existence of a giant planet orbiting within a few AU of a stellar remnant has profound implications for both the survival and possible regeneration of planets during…
Photometric and Spectral Signatures of 3D Models of Transiting Giant Exoplanets
Adam Burrows, Emily Rauscher, David Spiegel +1
Using a 3D GCM, we create dynamical model atmospheres of a representative transiting giant exoplanet, HD 209458b. We post-process these atmospheres with an opacity code to obtain t…
On constraining a transiting exoplanet's rotation rate with its transit spectrum
David S. Spiegel, Zoltan Haiman, B. Scott Gaudi
We investigate the effect of planetary rotation on the transit spectrum of an extrasolar giant planet. During ingress and egress, absorption features arising from the planet's atmo…
