Exoplanet Search and Characterization with the Proposed POET Canadian Space Mission
S. Metchev, J. Rowe, P. Miles-Páez +20
The Photometric Observations of Exoplanet Transits (POET) is a proposed micro-satellite mission dedicated to the characterization and discovery of transiting exoplanets. POET has b…
Model Predictions for the 2025 October Draconid Outburst
Auriane Egal, Paul Wiegert, Danielle E. Moser +2
The October Draconid meteor shower, produced by comet 21P/Giacobini-Zinner, is notorious for rare but intense outbursts, some exceeding rates of about 10 000 meteors per hour. In 2…
Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
A Planet as the Possible Cause of the HD 181327 Debris Disk Asymmetry
Chris Fox, Paul Wiegert
The debris disk around HD~181327 shows a significant asymmetry in its surface brightness profile when viewed in visible light. Observations from the Hubble Space Telescope STIS ins…
On the sensitivity of Apophis' 2029 Earth approach to small asteroid impacts
Paul Wiegert
Apophis' current trajectory takes it safely past our planet at a distance of several Earth radii on 2029 April 13. Here the possibility is considered that Apophis could collide wit…
Encounter circumstances of asteroid 99942 Apophis with the catalogue of known asteroids
Paul Wiegert, Ben Hyatt
Asteroid 99942 Apophis will pass near the Earth in April 2029. Expected to miss our planet by a safe margin, that could change if Apophis' path was perturbed by a collision with an…
Orbital and Physical Characteristics of Meter-scale Impactors from Airburst Observations
P. Brown, P. Wiegert, D. Clark +1
We have analysed the orbits and ablation characteristics in the atmosphere of 59 earth-impacting fireballs, produced by meteoroids one meter in diameter or larger, described here a…
A Study of the Orbits of the Logarithmic Potential for Galaxies
S. R. Valluri, P. A. Wiegert, J. Drozd +1
The logarithmic potential is of great interest and relevance in the study of the dynamics of galaxies. Some small corrections to the work of Contopoulos & Seimenis (1990) who used…
A Study of the Gravitational Wave Pulsar Signal with orbital and spindown Effects
S. R. Valluri, K. M. Rao, P. Wiegert +1
In this work we present analytic and numerical treatments of the gravitational wave signal from a pulsar which includes spindown. We consider phase corrections to a received monoch…
