Is Extraterrestrial Life Suppressed on Subsurface Ocean Worlds due to the Paucity of Bioessential Elements? [PDF]
Astronomical Journal, 2018 The availability of bioessential elements for “life as we know it”, such as phosphorus (P) or possibly molybdenum (Mo), is expected to restrict the biological productivity of extraterrestrial biospheres.

Microlensing and the Search for Extraterrestrial Life [PDF]
The Astrophysical Journal, 1999 Are microlensing searches likely to discover planets that harbor life? Given our present state of knowledge, this is a difficult question to answer. We therefore begin by asking a more narrowly focused question: are conditions on planets discovered via microlensing likely to be similar to those we experience on Earth?

Implications of Captured Interstellar Objects for Panspermia and Extraterrestrial Life [PDF]
Astronomical Journal, 2018 We estimate the capture rate of interstellar objects by means of three-body gravitational interactions. We apply this model to the Sun–Jupiter system and the Alpha Centauri A&B binary system, and find that the radius of the largest captured object is a ...
