A very interesting paper with 5 questions asked and addressed on these 25 hot jupiters reported. Reference paper, Five Key Exoplanet Questions Answered via the Analysis of 25 Hot-Jupiter Atmospheres in Eclipse,

My observation. The reference paper is very interesting and lists the 25 exoplanets studied. "2. Methodology Our study encompasses data for 25 hot Jupiters observed in eclipse with the HST-WFC3 G141 grism and Spitzer: CoRoT-1 b (CO1), HAT-P-2 b (HP2), HAT-P-7 b (HP7), HAT-P-32 b (HP32), HAT-P-41 b (HP41), HAT-P-70 b (HP70), HD 189733b (HD189), HD 209458b (HD209), KELT-1 b (K1), KELT-7 b (K7), KELT-9 b (K9), Kepler-13 A b (Ke13), TrES-3 b (Tr3), WASP-4 b (W4), WASP-12 b (W12), WASP-18 b (W18), WASP-19 b (W19), WASP-33 b (W33), WASP-43 b (W43), WASP-74 b (W74), WASP-76 b (W76), WASP-77 A b (W77), WASP-79 b (W79), WASP-103 b (W103), and WASP-121 b (W121). For WASP-121 b, we also add the available G102 grism."
I examined CoRot-1 b. Properties for CoRoT-1 b listed,
http://exoplanet.eu/catalog/corot-1_b/
Using the properties here I calculate P = 1.5163E+00 day. P listed as 1.509 day. In 1 Gyr period, this hot jupiter could complete 2.4089E+11 revolutions or more than 240 billion revolutions around the host star (in its current configuration).
Using a simple model where mass of hot jupiter = 0.5 Mjup, mass of host star = 0.95 Msun, e=0, a=0.05, P=4.1888E+00 day. In 1 Gyr period, 8.7196E+10 revolutions or more than 87 billion revolutions could be completed around a parent star for such a model hot jupiter. Hot jupiters are difficult to explain their origin and the 25 reported in this study, do not have their postulated primordial disc to observe and measure or migrations.
Postulated primordial discs to explain origin of hot jupiters and migration schemes moving them in much closer to parent stars (in some cases many AU distance changes) is not observable. Simulations run, making various input parameter guesses and changes results in a variety of outputs.
Using this exoplanet site,
The Extrasolar Planet Encyclopaedia — Catalog Listing (exoplanet.eu), 5014 exoplanets listed now.
I used SQL and found 953 with semi-major axis < 0.06 au from their parent star. There is potentially a large number of exoplanets moving around their parent stars very close, well inside where Mercury is at in our solar system, and with Jupiter size or more masses.
