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…

ACCESS: An optical transmission spectrum of the high-gravity, hot Jupiter HAT-P-23b

Ian C. Weaver, Mercedes López-Morales, Munazza K. Alam +11

We present a new ground-based visible transmission spectrum of the high-gravity, hot Jupiter HAT-P-23b, obtained as part of the ACCESS project. We derive the spectrum from five tra…

ACCESS: Confirmation of no potassium in the atmosphere of WASP-31b

Chima D. McGruder, Mercedes Lopez-Morales, Nestor Espinoza +12

We present a new optical (400-950nm) transmission spectrum of the hot Jupiter WASP-31b (M=0.48 MJ; R= 1.54 RJ; P=3.41 days), obtained by combining four transits observations. These…

ACCESS: A Visual to Near-infrared Spectrum of the Hot Jupiter WASP-43b with Evidence of , but no evidence of Na or K

Ian C. Weaver, Mercedes López-Morales, Néstor Espinoza +11

We present a new ground-based visual transmission spectrum of the hot Jupiter WASP-43b, obtained as part of the ACCESS Survey. The spectrum was derived from four transits observed…

LRG-BEASTS: transmission spectroscopy and retrieval analysis of the highly-inflated Saturn-mass planet WASP-39b

James Kirk, Mercedes Lopez-Morales, Peter J. Wheatley +5

We present a ground-based transmission spectrum and comprehensive retrieval analysis of the highly inflated Saturn-mass planet WASP-39b. We obtained low-resolution spectra ($R \app…

ACCESS: Ground-based Optical Transmission Spectroscopy of the Hot Jupiter WASP-4b

Alex Bixel, Benjamin V. Rackham, Dániel Apai +6

We present an optical transmission spectrum of the atmosphere of WASP-4b obtained through observations of four transits with Magellan/IMACS. Using a Bayesian approach to atmospheri…

ACCESS: A featureless optical transmission spectrum for WASP-19b from Magellan/IMACS

Néstor Espinoza, Benjamin V. \ Rackham, Andrés Jordán +13

The short period (-day) transiting exoplanet WASP-19b is an exceptional target for transmission spectroscopy studies, due to its relatively large atmospheric scale-height ($\…

The Transiting Exoplanet Community Early Release Science Program for JWST

Jacob L. Bean, Kevin B. Stevenson, Natalie M. Batalha +99

The James Webb Space Telescope (JWST) presents the opportunity to transform our understanding of planets and the origins of life by revealing the atmospheric compositions, structur…
