The plausibility of origins scenarios requiring two impactors

Proceedings of the Royal Society of London Series A (in press)

One potential way to achieve the conditions required for several prebiotic chemical scenarios, is via the cometary delivery of hydrogen cyanide, followed by the collision of a secondary, smaller body. Here, we demonstrate, using constraints on Earth's early bombardment, that these scenarios are extremely unlikely after 4.0Gya.

Can comets deliver prebiotic molecules to rocky exoplanets?

Proceedings of the Royal Society of London Series A

The cometary delivery of prebiotic feedstock molecules requires impacts at very low velocity. In this work, we use both an analytical model and N-body simulations, to show that the lowest velocity impacts occur in tightly packed planetary systems around high-mass (i.e., Solar-mass) stars.

WD 0141-675: a case study of how to follow-up astrometric planet candidates around white dwarfs

Monthly Notices of the Royal Astronomical Society

This work combines spectroscopic and photometric data of the polluted white dwarf WD 0141−675, which has a now retracted astrometric super-Jupiter candidate, and investigates the most promising ways to confirm Gaia astrometric planetary candidates and obtain follow-up data.
