Receipt: # 5806-1 ----- Attempting Submission 2 (Tue Mar 26 23:58:51 GMT 2024) ----- 0 Can Lyman-alpha transits quantitatively test atmospheric escape models? The loss of sub Neptune H/He envelopes is believed to be a key mechanism for forming super Earths and producing the bimodal radius distribution of small planets. The two leading hypotheses, photoevaporation (PE) and core powered mass loss (CPML), both produce results consistent with the observed exoplanet population, yet imply dramatically different atmospheric histories of small planets. Thus, escape models need to be validated with direct observations. Recently, it has been suggested that Lyman-alpha tail lengths provide such a test. Before they can be used to analyze escape processes across a large population of planets, these tail models must be validated. In this framework, the Lyman-alpha tail length decreases with increasing EUV flux. We will test this hypothesis by extending the range of EUV flux probed by full-duration Lyman-alpha transits with an additional planet. We will conduct all observations with STIS G140M/1222, a configuration with extensive heritage that limits contamination by geocoronal Lya airglow. HD 15337 has been previosuly observed with STIS G140L. To measure the tail, we stagger five 4-orbit visits. To guard against evolution in the out-of-transit Lya flux between these sets, we will conduct one-orbit pre-transit visit approximately 17-24~h (again, timing limited by SAA passages) ahead of each 4-orbit transit visit. Dr. Schreyer is the developer of a novel phenomenological model enabling rapid simulations of Lyman-alpha transits (Schreyer et al. 2024). Dr. Loyd has extensive experience in the reduction and analysis of HST data for stellar activity and planetary transits (e.g., Loyd et al. 2017, 2018a,b, 2023) and will carry out data reduction for the program. Drs. Owen, Murray-Clay, and Schlichting are experts in modeling exoplanetary escape (e.g., Owen and Alvarez, 2016; Murray-Clay et al., 2009, McCann et al. 2019, Gupta & Schlichting et al. 2019). Dr. Owen modeled the atmospheric escape of the planets for which we propose observations and is responsible for an early prediction of the exoplanet radius gap (Owen and Wu, 2013). The remainder of the team has expertise in stellar acitivy (Shkolnik, Barman), including modeling activlity-generated emission via PHOENIX models (Barman); and the atmospheres of small planets (Swain).

Therefore, we require the Transit 5 (10) (which is our furthest post-optical transit exposure) to be observed before Transit 1 (02), Transit 2 (04), Transit 3 (06) and Transit 4 (08). This will allow us to adjust the phases of these observations accordingly if we do not see the egress in Transit 5.
