Eric Agol @ericagol.bsky.social · 04/09/2025If a title includes a question mark, the answer usually is 'no.' 000
Eric Agol @ericagol.bsky.social · 04/09/2025Yes, and I miswrote above - the density of the star would be lower, not higher, if you assumed that there were a single short-period planet instead of a chain of identical planets. 010

Eric Agol @ericagol.bsky.social · 04/09/2025Yes - the transit duration would be longer, so one would infer a larger density for the star (if you could measure the impact parameter and orbital eccentricity vector). I would also expect the RV of the star to be dramatically reduced. 110
Eric Agol @ericagol.bsky.social · 02/09/2025If this were a transiting planet system, and one modeled it as a single transiting planet w/ P = 0.039 years, one would infer the wrong density for the star (I don't think there would be TTVs...). Would this be worth searching for based on transiting planets with anomalous host-star densities? 200
