description: Jupiter.s North Equatorial Belt (NEB) comma  a dark reddish-brown band just to the north of the Equatorial Zone comma  regularly varies in width and color. The current NEB cycle is more extreme than any previous transition since 1928 comma  and it includes rarely seen convective eruptions at an active longitude moving around the planet. The current convective activity is a stealth superstorm comma  because it shares the long-term activity of a major superstorm comma  but it does not reach the same high altitudes. This newly recognized transitional case between the sporadic minor convective storms common in Jupiter.s belts (but never detected on Saturn) comma  and the major convective superstorms sending plumes up to high altitudes in the atmospheres of both gas giants comma  probes differences in convective styles related to the deep water abundance.   HST observations of the stealth superstorm system would define 3D cloud structure by mapping deep water clouds and constraining plume heights. Observations require 200-km scale resolution (inaccessible to ground-based visible wavelength imaging) to distinguish anisotropic cloud structure in the stealth superstorm region and near the Juno spacecraft track. Juno.s microwave observations have revealed that spectacular convective storms in 2016 (observed at cloud tops in the visible and infrared) comma  are connected to changes in ammonia and temperature at great depth comma  both above and below the water-cloud layers. Data from Juno collected in 2021 and 2022 will test whether deep changes also accompany the current NEB cycle comma  with its newly recognized stealth superstorm activity.

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

description: We propose to use WFC3-UVIS to study the multiplicity of a sample of 60 young free-floating planets recently identified in the nearby Upper Scoand Taurus associations. The formation of these exotic objects is still largely an open question. Have they been ejected or  stripped away from the planetary system in which they were bornquestionMark Or did they form isolated in a similar way to stars from the collapse and contraction of a tiny molecular clumpquestionMark WFC3-UVIS unique resolution and sensitivity will allow us to detect companions as close as virgul5au comma  over a completely unexplored range of primary masses. The proposed comprehensive study of multiplicity among this unique sample of young (1 to 10Myr) Upper Sco and Taurus free floating planets will provide serious constraints for the theories of formation and allow to better understand the respective contributions of these different processes to the final free-floating planet population comma  with important implications on brown dwarf and planet formation.

description: The WFC3-IR detector exhibits a non-linear response to incident flux. The data reduction pipeline provides a correction for the non-linearity comma  which depends on accurate characterization of the response of the detector. To monitor the non-linearity of the WFC3-IR detector comma  we use a dark observation followed by two internal flats using the Tungsten lamp at different sampling rates comma  and a trailing dark. Any changes measured in the non-linearity will be updated in the calibration reference file comma  crucial to providing a correction for accurate photometry. This program is a continuation of the cycle 29 (program 16576) linearity calibration program.

description: Observations of the population of ultra luminous X-ray sources has revealed that at least a subset of this group contains a neutron star primary. Thus comma  dramatically demonstrating the viability of super-Eddington accretion for this source class. However comma  the physics of these super-Eddington accretion flows are poorly understood with the sources typically lying at Mpc distances. The population of Galactic Be-X-ray binaries (BeXRBs) are known to have giant outbursts that enter the super-Eddington regime and promise the opportunity to learn much about this mode of accretion. Herein comma  we propose to obtain simultaneous high resolution X-ray comma  UV and radio spectroscopy of the next bright Galactic BeXRB to enter a giant outburst when the neutron star will be accreting in the super-Eddington regime.

description: The Space Telescope Science Institute (STScI) Director has decided to devote up to 1000 orbits of Director.s Discretionary time in observing Cycles 27-29 to a new Hubble Ultraviolet Legacy program focused on star formation and associated stellar physics. This new program comma  ULLYSES (UV Legacy Library of Young Stars as Essential Standards) comma  will provide a UV spectroscopic reference sample of young (< 10 Myr) high- and low-mass stars. It will target over virgul150 OB stars in the Magellanic Clouds and lower metallicity galaxies in the Local Group comma  and virgul40 T Tauri stars and brown dwarfs in the Milky Way. In addition comma  ULLYSES will monitor 4 typical T Tauri stars over different rotational phases through at least three rotation periods comma  and over timescales of months to years. The resulting library will provide template spectra of massive stars at metallicities substantially below the well studied comma  while the low mass sample will cover a wide range of ages comma  accretion rates comma  and masses comma  including objects down to well below 0.5 M_sun. The legacy of this large UV dataset on the first 10 Myr of stellar evolution will be enhanced by complementary datasets obtained by the scientific community. In addition to the core goals of the program related to stellar astrophysics of low and high mass stars comma  this data will also enable exciting science in the fields of ISM comma  CGM comma  jets comma  and exoplanets. ULLYSES will be modeled after the Frontier Fields programdoublePoint all data obtained will be non-proprietary. The implementation team at STScI is developing high-level science data products and a sophisticated database and website for disseminating data from the ULLYSES program and ancillary datasets for the ULLYSES target sample from space and ground-based facilities.

description: Abell 1185 is a nearby example of a rich galaxy cluster still undergoing violent hierarchical assembly. Its brightest member galaxy comma  NGC 3550 comma  is offset by 150 kpc from the cluster.s dynamical center and is in the throes of cannibalizing several neighbors. Abell 1185 is also home to a population of intergalactic globular clusters comma  as well as the interacting system Arp 105 comma  a spectacular collision between two galaxies that has spawned a compact region of intense star formation known as Ambartsumian.s Knot as well as a 100-kpc-long tidal tail with embedded star clusters and newborn dwarf galaxies. Abell 1185 offers a unique opportunity to witness the ongoing birth of a dynamically young cluster and its constituents comma  a present-day analog to cluster formation at earlier epochs. We propose to carry out a comprehensive WFC3+ACS imaging survey of A1185 to learn more about the ongoing creation of galactic and intergalactic stellar populations in this dynamic environment. The resulting dataset will be of comparable legacy value to the ACS Treasury Survey of the Coma Cluster (GO 10861) for a fraction of the investment of time comma  providing a snapshot of a rich cluster environment that represents an important earlier stage in galaxy cluster evolution.

description: There are only two globular clusters where a modest investment of HST time can yield a high-precision measurement of trigonometric parallaxdoublePoint NGC6397 and M4. The parallax to NGC6397 has been measured successfully with HST to 2% uncertainty. An important HST legacy would be the completion of this pair comma  by measuring the M4 parallax while HST can still do so.  In the context of the Galaxy.s globular cluster system comma  these two clusters are complementary. NGC6397 is ancient (13 Gyr) and metal-poor (CORCHETE_OPENFe-HCORCHETE_CLOSE=-2.02) comma  while M4 is younger (11.5 Gyr) and of intermediate metallicity (CORCHETE_OPENFe-HCORCHETE_CLOSE=-1.15). NGC6397 is a frequent fiducial for stellar population models comma  while M4 hosts a rich set of RR Lyrae stars that can be used to better calibrate the period-luminosity relationship. The utility of each cluster as a population template and calibrator depends critically upon the distance uncertainties. The scarcity of population anchors in this regime is in contrast to the parameter space at younger ages (< 10 Gyr) and higher metallicities (CORCHETE_OPENFe-HCORCHETE_CLOSE > -1) comma  where many open clusters have high-precision parallaxes.  In a broader context comma  these two clusters represent an essential independent check on the parallaxes from the Gaia mission comma  which currently suffer from significant systematic errors on global comma  intermediate (20 degrees) comma  and small (1 degree) scales comma  hampering distances to the Galaxy.s globular clusters. If these errors are eventually resolved comma  HST parallaxes to globular clusters comma  independent of Gaia with distinct methodology comma  will provide an important validation. The observations we propose here will help anchor the distances to the entire globular cluster system of the Milky Way.

description: Ganymede and Callisto are primary targets of ESA.s JUpiter Icy Moon Explorer (JUICE) and NASA.s Europa Clipper missiondoublePoint Callisto will be visited with a total of about 20 flybys. Ganymede will be the first planetary moon to be orbited by a spacecraft (JUICE). Today comma  the atmospheres of the two icy moons are only loosely constrained by observations. Oxygen comma  the domimant atmospheric species comma  is observable only through faint electron-excited emissions comma  complicating derivation of reliable neutral gas abundances or distribution due to poorly constrained electron properties.  STIS spectral imaging has recently proven to be a sensitive tool for investigating Io and Europa while in transit of JupiterdoublePoint Atmospheres and plume abundances are probed through extinction of the bright Jupiter Ly-alpha background - independently of electron properties. The observing geometry now during HST Cycle 28 provides optimal conditions to also observe Ganymede and Callisto in transit of Jupiter. Both moons have long (>3.5 h) transits near the Ly-alpha-bright equator of the planet comma  a condition that is fulfilled only every virgul6 years. We propose to observe Ganymede and Callisto during one transit of Jupiter each with two consecutive HST orbits. The observations will provide the most precise measurements of the H atmospheres and the first ever spatially resolved constraints on atmospheric H2O - from sublimation or outgassing - for the two largest moons of Jupiter. The transit geometry provides the unique opportunity to measure hemispheric differences in the atmospheres comma  which likely arise from the moons. surface volatile distributions as known via albedo dichotomies between the trailing and leading sides.

description: In the Kepler database lies an important and yet unexplored opportunity. The two d_commasuper-aperturesd_comma centered on the star clustersdoublePoint NGC 6791 and NGC 6819 - each containing several thousands stars - have been monitored almost continuously for over 4 yrs. If their stellar populations could be disentangled comma  then these Kepler datasets would be of groundbreaking importance to assess planet occurrence rates in two uniquely large groups of homogeneous and coeval stars.  We propose to obtain high-resolution HST images within these two super-aperture fields and use a well tested method (already proved successful) to combine Kepler lightcurves with HST source information. The unmatched HST image quality will provide a homogeneous comma  complete comma  and color-complete input list which will enable extracting Kepler light curves of all the objects. Furthermore comma  HST allows us to obtain proper motions linked to the Gaia system and membership for all these stars.  The combined data will provide about 25 comma 000 lightcurves - increasing the total Kepler sample by 15%! Based on the latest planet occurrence rates we expect to find over 70 transiting planets -- virgul40 in the solar-metallicity NGC 6819 comma  and about 30-50 in the super-solar metallicity NGC 6791.  Our program will greatly enhance the Kepler mission.s yield comma  boost the number of known transiting planets comma  and will allow a direct test of the planet occurrence rate-metallicity relationship in uniquely homogeneous and well-characterized samples. The proposed data will also enable many other investigations comma  enhancing the legacy and the scientific impact of both the HST and the Kepler missions comma  and target selections for future JWST and ARIEL follow-ups.

description: Long time base observations of the outer planets are critical in understanding the atmospheric dynamics and evolution of the gas giants.  We propose yearly monitoring of each giant planet for the remainder of Hubble.s lifetime to provide a lasting legacy of increasingly valuable data for time-domain studies.  The Hubble Space Telescope is a unique asset to planetary science comma  allowing high spatial resolution data with absolute photometric knowledge.  For the outer planets comma  gas-ice giant planets Jupiter comma  Saturn comma  Uranus and Neptune comma  many phenomena happen on timescales of years to decades comma  and the data we propose are beyond the scope of a typical GO program.  Hubble is the only platform that can provide high spatial resolution global studies of cloud coloration comma  activity comma  and motion on a consistent time basis to help constrain the underlying mechanics.
