Characterizing the Detected Atmospheric Escape of a Pair of Small Sub-Neptunes HST recently discovered a neutral hydrogen outflow from a planet in the transitional space between the sub-Neptune and super-Earth populations, TOI-776 b. Its nearby sub-Neptune sibling, TOI-776 c, also exhibits hydrogen loss. These two planets represent a crucial link between the sub-Neptune and super-Earth populations, long theorized to be the result of an initially continuous population of planets that evolved into two branches, with one losing their primordial H/He atmospheres, shrinking to the size of their rocky cores. Within its remaining life, TOI-776 b has a roughly 15% chance of completing the transition into a super-Earth by losing most of its remaining H/He atmosphere, whereas TOI-776 c will stably reside in the sub-Neptune population. The proposed program builds upon this recent discovery, moving from detection to a thorough characterization of the planetary outflows. These observations have two primary objectives: imposing an added constraint on outflow models by observing the Lyman-alpha transit egress and measuring the neutral O and singly-ionized C content. The results will provide insight into how small planets are shaped and how their atmospheres are chemically enriched by atmospheric escape. We will use a combination of STIS/G140M/1222 observations to measure the Lya transit from ingress through egress and COS/G130M/1222 observations to measure the transit depth in O I and C II. Although recent work has demonstrated the ability to recover Lya profiles from airglow contamination with COS/G130M, TOI-776 does not pass the bright object protection limits set forth in COS-ISR 2017-01 for flaring Lya conditions. Using the 1222 cenwave places Lyha in the detector gap, ensuring instrument safety. To sample the egress of each Lya transit, we will use 5-orbit sequences of STIS observations. Passages through the South Atlantic Anomaly (SAA) limit STIS observations to 5 orbit sequences. A single sequence is sucient for the short predicted duration of TOI-776 b's transit. Two sequences must be staggered to sample TOI-776 c's extended egress. The initial sequence will sample pre-transit and ingress. The second will sample egress, with a 2-orbit baseline set 17-24 h (one SAA passage) ahead to compensate for time-variability in the baseline due to the star's 34.4 d rotation (Luque et al., 2020). We will use the 52x0.2" slit with STIS, which ensures systematics from slit breathing are below the >10% precision estimated from the existing observations. Based on the previous observations, we expect 1800-2150 s of science exposure in the first HST-orbit of each visit after target acquisition and other overheads, with the science exposures of subsequent orbits likely lasting 2500 s. We will conduct COS/G130M observations in three sets of 2-orbit visits for each planet. Each 2-orbit visit will sample baseline and mid-transit within a single observing window outside of the SAA, enabling the greatest sensitivity to O and C+ in the outflow. We have verified that all visits are schedulable within phase constraints using the APT. We will constrain the observations to occur with a month of when the star appears maximally redshifted relative to Earth to mimize noise at transit wavelengths. For G130M, we will also constrain that observations be taken during low airglow conditions (per special requirement stated in the proposal). R. O. Parke Loyd has extensive experience in the reduction and analysis of HST data, with nine first-author papers published using such data since 2014. He is lead author of the discovery paper of the TOI-776 Lya transits. Drs. James Owen, Ruth Murray-Clay, and Hilke Schlichting are leaders in the field of exoplanetary atmospheric scape and sub-Neptune evolution (e.g., Owen and Alvarez, 2016; Murray-Clay et al., 2009; Gupta and Schlichting 2019). Dr. Owen was one of the founders of the XUV evaporation theory and Dr. Schilchting of core-powered mass loss. Dr. Owen's student Ethan Schreyer developed the outflow model that will be used in this work. Dr. Rogers is a postdoctoral researcher working with Dr. Schlichting and is an expert in population modeling under the influence of atmospheric escape. He developed the evolutionary model that will be used in this work. Dr. Murray-Clay and her student Madelyn Broome have developed the 3D and 1D outflow models that will be used in this work. Dr. Allison Youngblood is the PI of multiple HST programs to study exoplanets and their host stars in the UV, including a large survey of the UV emission from JWST Cycle 1 transiting exoplanet host stars (GO-16701) and a Lyman alpha transit of the sub-Neptune TOI-1231b. Dr. Evgenya Shkolnik has been studying exoplanets and the stellar activity of their host stars, including star-planet interactions, for over 20 years, ranging from systems around Sun-like stars down to the lowest mass M dwarfs, including extensive studies of the Sun-as-a-star. She is also the PI or Co-I of several HST programs, including those studying the UV evolution of K and M stars. Dr. David Wilson is a PI of multiple previous HST programs obtaining ultraviolet observations of stars using all four active science instruments, and has published many first-author papers based on HST data. Drs. Kevin France, Christian Schneider, and David Ardila are experts in UV instrumentation and observations. Drs. Sarah Peacock and Travis Barman are experts in modeling stellar and giant planet atmospheres. A modified PHOENIX model they have developed can be used to predict the EUV emission of a low-mass star by matching the model-simulated FUV emission to observations (Peacock et al. 2019). Dr. Girish Dvvuri is an expert in DEM modeling, a complementary method to PHOENIX models. Drs. Johanna Teske and Natasha Batalha have experience in characterizing small planets through transit and RV observations, including specifically the TOI-776 planets through JWST and ground-based RV observations. She also has experience studying exoplanet host stars through ground-based high-resolution spectroscopy and imaging.
