ACCESS, LRG-BEASTS, & MOPSS: Featureless Optical Transmission Spectra of WASP-25b and WASP-124b

Chima D. McGruder, Mercedes López-Morales, James Kirk +14

We present new optical transmission spectra for two hot Jupiters: WASP-25b (M = 0.56~M; R = 1.23 R; P =~3.76 days) and WASP-124b (M = 0.58~M; R = 1.34 R; P = 3.37 d…

The Similar Seven: A set of very-alike exoplanets to test correlations between system parameters and atmospheric properties

Chima D. McGruder, Mercedes López-Morales, Rafael Brahm +1

Studies of exoplanetary atmospheres have found no definite correlations between observed high altitude aerosols and other system parameters. This could be, in part, because of the…

ACCESS: Tentative detection of HO in the ground-based optical transmission spectrum of the low-density hot Saturn HATS-5b

Natalie H. Allen, Néstor Espinoza, Andrés Jordán +13

We present a precise ground-based optical transmission spectrum of the hot-Saturn HATS-5b ( K), obtained as part of the ACCESS survey with the IMACS multi-object spec…

ACCESS: Confirmation of a Clear Atmosphere for WASP-96b and a Comparison of Light Curve Detrending Techniques

Chima D. McGruder, Mercedes López-Morales, James Kirk +11

One of the strongest features was observed in WASP-96b. To confirm this novel detection, we provide a new 475-825nm transmission spectrum obtained with Magellan/IMACS,…

ACCESS & LRG-BEASTS: a precise new optical transmission spectrum of the ultrahot Jupiter WASP-103b

James Kirk, Ben Rackham, Ryan MacDonald +17

We present a new ground-based optical transmission spectrum of the ultrahot Jupiter WASP-103b (K). Our transmission spectrum is the result of combining five new tran…
