title: The Molecular Cloud Lifecycle I: Constraining H2 formation and dissociation rates with observations

description: Molecular clouds (MCs) are the birthplaces of new stars in galaxies. A key component of MCs are photodissociation regions (PDRs), where far-ultraviolet radiation plays a crucial role in determining the gas's physical and chemical state. Traditional PDR models assume chemical steady state (CSS), where the rates of H2 formation and photodissociation are balanced. However, real MCs are dynamic and can be out of CSS. In this study, we demonstrate that combining H2 emission lines observed in the far-ultraviolet or infrared with column density observations can be used to derive the rates of H2 formation and photodissociation. We derive analytical formulae that relate these rates to observable quantities, which we validate using synthetic H2 line emission maps derived from the SILCC-Zoom hydrodynamical simulation. Our method estimates integrated H2 formation and dissociation rates to within 29% accuracy. Our simulations cover a wide dynamic range in H2 formation and photodissociation rates, showing significant deviations from CSS, with 74% of the MC's mass deviating from CSS by a factor greater than 2. Our analytical formulae can effectively distinguish between regions in and out of CSS. When applied to actual H2 line observations, our method can assess the chemical state of MCs, providing insights into their evolutionary stages and lifetimes.

title: Evidence for Variable Accretion onto PDS 70 c and Implications for Protoplanet Detections

description: Understanding the processes of planet formation and accretion in young systems is essential to unraveling the initial conditions of planetary systems. The PDS 70 system, which hosts two directly imaged protoplanets, provides a unique laboratory for studying these phenomena, particularly through Hα emission, a commonly used accretion tracer. We present multi-epoch observations and examine the variability in accretion signatures within this system, focusing on PDS 70 b and c. Using Hubble Space Telescope narrowband Hα imaging from 2020 and 2024, we achieve high signal-to-noise detections of these planets and reveal significant changes in Hα flux. For PDS 70 c, the Hα flux more than doubled between 2020 and 2024. The trend is consistent with the one identified in recently published MagAO-X data, further confirming that PDS70c has become significantly brighter in Hα between 2023 March and 2024 May. The observed variability suggests dynamic accretion processes, possibly modulated by circumplanetary disk properties or transient accretion bursts. High-amplitude variability in PDS 70 c motivates simultaneous monitoring of multiple accretion tracers to probe the mechanisms of mass growth of gas giant planets. We quantify the impact of variability on the detectability of protoplanets in imaging surveys and emphasize the need for continued and regular monitoring to accurately assess the occurrence and characteristics of young, forming planets

title: Kiladze Caldera: A possible "supervolcano" on Pluto

description: In data from the New Horizons encounter with Pluto in 2015, attention was called to a crater named Kiladze and its surroundings because of the water ice spectral properties, which contrast with the primarily CH4 regional surface composition. The H2O ice carries the spectral signature of an ammoniated compound, similar to that seen at two other sites on Pluto where cryovolcanism has been identified. The faulted structure of Kiladze, including shaping by numerous collapse pits and the distorted shape of the crater, are compatible with the surroundings in Hayabusa Terra, east of Spunik Planitia. They are compatible with an interpretation as a resurgent caldera formed in a once- active cryovolcanic period that appears to be significantly more recent than the overall age of the planet's surface, possibly in the last several million years. In view of the size of the caldera and the large scale of the surrounding distribution of H2O ice, we propose that Kiladze is a "supervolcano" in which one or more explosive events has scattered more than ~1000 km3 of icy cryomagma erupted from the interior onto the surface.

title: Evaluating Current Statistical and Dynamical Forecasting Techniques for Seasonal Coastal Sea Level Prediction

description: The need for skillful seasonal prediction of coastal sea level anomalies (SLAs) has become increasingly evident as climate change has increased coastal flooding risks. Here, we evaluate nine current forecast systems by calculating deterministic and probabilistic skill from their retrospective forecasts (“hindcasts”) over 1995-2015, for lead times up to 6-9 months, at two United States tide gauge stations (Charleston, SC and San Diego, CA). Additionally, we assess local skill enhancement by two post-processing/downscaling techniques: an observationally based multivariate linear regression and a hybrid dynamical approach convolving sea-level sensitivity to surface forcings with predicted surface forcing variations. All these approaches face challenges stemming from whether modeled SLAs sufficiently represent observed local coastal SLA variations because of ocean model limitations and inadequacies in model initialization and ensemble spread. Some of these issues also complicate the ability of the post processing techniques to improve probabilistic skill, even though they do somewhat improve deterministic skill. In general, deterministic hindcast skill is considerably higher for San Diego than Charleston, as expected from the stronger influence of ENSO. However, ensemble spread metrics such as forecast reliability and sharpness remain low for both locations, highlighting model deficiencies in representing uncertainty. Additionally, evaluating how well any technique predicts seasonal coastal sea level variations is complicated by the forced trend component, particularly how it is estimated. Moreover, model skill is matched by a stochastically-forced multivariate linear prediction model constructed from observations, suggesting that substantial improvement remains for predicting coastal seasonal SLAs, which could also include leveraging other predicted fields, including sea level pressure and prevailing winds.

title: Setting the Stage for Uranian Seismology from Rings and Radial Velocities

description: A Uranus orbiter would be well positioned to detect the planet's free oscillation modes, whose frequencies can resolve open questions about Uranus's weakly constrained interior. We calculate the spectra that may manifest in resonances with ring orbits or in Doppler imaging of Uranus's visible surface, using a wide range of new interior models that satisfy the present constraints. Recent work has shown that Uranus's fundamental (f) and {internal} gravity (g) modes have appropriate frequencies to resonantly confine Uranus's narrow rings, which in most cases have no clear confinement mechanism. We show that even a single low spherical harmonic degree f or g mode detected in imaging or occultations can constrain Uranus's core structure, compared to the degenerate solution space permitted by current or more precise orbiter-derived zonal gravity constraints. Degeneracies persist due to possible confusion between f, g, and interface modes; in this respect a second mode detection would clarify the interpretation dramatically. If Uranus has a frozen core that low degree f modes cannot penetrate, their frequencies are reduced and they are more likely to resonate among the narrow rings. A single high degree f mode resonating in the rings would constrain Uranus's unknown interior rotation period. The different technique of Doppler imaging seismology requires specialized instrumentation but could deliver many more detections, with best sensitivity to acoustic (p) mode oscillations at mHz frequencies. Their deviations from uniform spacing can be used to locate density interfaces in Uranus's interior, such as that of a sharp core boundary. Shallower nonadiabaticity and condensation layers complicate this approach, but we show how higher order frequency differences based on the same spectra can be analyzed to disentangle deep and near-surface effects.

title: New Impacts on Mars: Systematic Identification and Association with InSight Seismic Events

description: The InSight lander represents a unique opportunity to correlate seismic data with impact events identified in orbital images, enabling the characterization of the physical properties of the martian crust and mantle. Here, we present the first comprehensive catalog of impacts that occurred during the InSight mission within a 50° radius around the lander. We use a machine learning-enabled approach to identify 123 date-constrained impacts with diameters between ~1 and 22.5 m. We estimate an impact rate of 2.7×10−6/km2/year for &gt;3.9 m effective diameter, which is ~1.6 to ~2.5 times higher than previously derived for Mars. We identify 49 seismic events with one or several potential impact match(es) including a 21.5 m crater located near Cerberus Fossae. Our catalog will enable a more accurate characterization of the propagation of seismic body waves at intermediate distances to InSight (5 to 50°), with major implications for estimates of other seismic event distances.

title: Emission from multiple molecular isotopologues in a high-inclination protoplanetary disk

description: We present a MIRI-MRS spectrum of the high-inclination protoplanetary disk around the solar-mass (K0) star MY Lup, obtained as part of the JWST Disk Infrared Spectral Chemistry Survey (JDISCS). The spectrum shows an unusually weak water emission spectrum for a disk around a star of its spectral type, but strong emission from CO2, HCN, and isotopologues of both molecules. This includes the first ever detection of C18O 16 O and H13CN in an inner disk, as well as tentative detections of C17O 16O and HC15 N. Slab modeling provides molecular temperatures, column densities and emitting areas of the detected molecules. The emitting molecular gas is cold compared to that of other observed protoplanetary disk spectra. We estimate the isotopologue ratios of CO2 and HCN, albeit with significant uncertainty. We suggest that the unusual spectrum of MY Lup arises from a combination of inner disk clearing, which removes emission from warm water, and its nearly edge-on inclination, which enhances line-of-sight column densities, although unusual chemistry may also be required. MY Lup’s spectrum highlights the potential to detect and measure trace isotopologues to study isotopic fractionation in protoplanetary disks; observations at higher spectral resolving power is needed to constrain the isotopologue ratios to greater precision.

title: Editorial: Europa Clipper – A Mission to Explore Ocean World Habitability

description: Europa, one of Jupiter’s four largest moons, was discovered by Galileo Galilei in 1610. Early observations revealed its bright, icy surface, sparking curiosity about the details of its composition. In the 1970s, NASA’s Pioneer and Voyager missions provided the first close-up images, showing Europa’s smooth, relatively crater-sparse surface, suggesting active geology. These missions hinted at a subsurface ocean beneath the ice. Additional evidence for the presence of an ocean was supplied by the Galileo spacecraft in the 1990s through magnetic field data and surface analysis. Galileo imaging data also revealed the presence of high albedo plains, chaotic terrains, ridges, and lineae, likely formed by ice movement and possible interactions with liquid water below. More recent observations, including those of potential water plumes, have strengthened the idea that Europa’s putative subsurface ocean may harbor the conditions conducive for biological activity. These discoveries have made Europa a prime target for astrobiological exploration, and NASA’s Europa Clipper mission was designated to investigate Europa’s habitability.

title: Glycine Partitioning in Frozen Putative Europan Brines

description: Europa is a prime candidate in the search for extraterrestrial life due to its potential habitability, which is supported by a sustained energy source, the availability of essential biocritical elements, and an extensive subsurface ocean of liquid water. This study examines the behavior of glycine, an amino acid, in simulated Europan brines subjected to various freezing processes to understand its potential distribution and preservation on Europa. Equimolar brines containing 0.1 M of Na+, Cl-, Mg2+, SO₄2-, and glycine (C₂H₅NO₂) were exposed to flash- and slow-freezing conditions to simulate different emplacement processes onto Europa’s icy surface environment. Analyses using micro-Raman imaging revealed that glycine preferentially associates with salt phases rather than water-ice, where the freezing mechanism (i.e., cooling rate) influences both the species of salt that precipitates and their spatial distribution. These findings suggest that salt-rich ice particles could be valuable targets for remote and in situ detection of organic molecules and potential biosignatures in future explorations. Notably, solid CO₂ was observed in isolated inclusions within slow-frozen samples, suggesting a glycine-driven mechanism for CO₂ entrapment during freezing. Diffuse reflectance infrared measurement of the observed CO2 showed some consistencies but did not produce an identical match of the recent JWST spectra of CO2 on Europa’s surface (Trumbo et al., 2023), implying that this mechanism is unlikely to be the pathway for CO2 production on this icy body.
