The need for a multi-purpose, optical–NIR space facility after HST and JWST by Jahnke, Knud, Krause, Oliver, Rix, Hans-Walter, Courbin, Frédéric, Fontana, Adriano, Heymans, Catherine, Martin, Nicolas, Oesch, Pascal, Taylor, Andy, Gaudi, B. S, Kiessling, Alina, Mennesson, Bertrand, Seager, Sara, Stern, Daniel, Warfield, Keith

“…Abstract In the early 2030s, after the end of operations for the epochal Hubble Space Telescope and the long-anticipated James Webb Space Telescope, astrophysics will lose access to a general purpose high-spatial resolution space observatory to cover the UV–optical–NIR wavelength range with a variety of imaging bandpasses and high-multiplexing mid-resolution spectroscopy. …”

Discovery and Characterization of Transiting Super Earths Using an All-Sky Transit Survey and Follow-up by the James Webb Space Telescope by Seager, Sara, Winn, Joshua Nathan, Deming, Drake, Miller-Ricci, Eliza, Clampin, M., Lindler, D., Greene, Tom, Charbonneau, David, Laughlin, G. P., Latham, David W., Ennico, K., Ricker, George R

“…We evaluate the prospects for an all-sky transit survey targeted to the brightest stars, that would find the most favorable cases for photometric and spectroscopic characterization using the James Webb Space Telescope (JWST). We use the proposed Transiting Exoplanet Survey Satellite (TESS) as representative of an all-sky survey. …”

“…Although the Transiting Exoplanet Survey Satellite (TESS) primary mission observed the northern and southern ecliptic hemispheres, generally avoiding the ecliptic, and the Kepler space telescope during the K2 mission could only observe near the ecliptic, many of the K2 fields extend far enough from the ecliptic plane that sections overlap with TESS fields. …”

A PRECISE WATER ABUNDANCE MEASUREMENT FOR THE HOT JUPITER WASP-43b by Kreidberg, Laura, Bean, Jacob L., Desert, Jean-Michel, Line, Michael R., Fortney, Jonathan J., Madhusudhan, Nikku, Stevenson, Kevin B., Showman, Adam P., Charbonneau, David, McCullough, Peter R., Seager, Sara, Burrows, Adam, Henry, Gregory W., Williamson, Michael, Kataria, Tiffany, Homeier, Derek

“…We present a precise determination of the water abundance in the atmosphere of the 2 M Jup short-period exoplanet WASP-43b based on thermal emission and transmission spectroscopy measurements obtained with the Hubble Space Telescope. We find the water content is consistent with the value expected in a solar composition gas at planetary temperatures (0.4-3.5 × solar at 1σ confidence). …”

HD 219134 Revisited: Planet d Transit Upper Limit and Planet f Transit Nondetection with ASTERIA and TESS by Seager, Sara, Knapp, Mary E., Krishnamurthy, Akshata, Huang, Chelsea X., Badenas, Mariona, Shporer, Abraham-Avi, Ricker, George R, Vanderspek, Roland K, Fausnaugh, Michael, Glidden, Ana

“…Ground-based searches for transits of planets beyond b and c are not feasible because of the infrequent transits, long transit duration (~5 hr), shallow transit depths (<1%), and large transit time uncertainty (~half a day). We use the space-based telescopes the Arcsecond Space Telescope Enabling Research in Astrophysics (ASTERIA) and the Transiting Exoplanet Survey Satellite (TESS) to search for transits of planets f (P = 22.717 days and M sin i = 7.3 ± 0.04M ) and d (P?…”
