This new submission is an update of the previous submission, done to follow the advice to use the 0.2x0.09 slit aperture for the STIS science exposures (instead of the 31x0.05NDA slit previously chosen for too conservative safety reason). For our target the Count rate entire detector is about ~160,000 (counts/s). This is below the bright limit at 200,000 counts/s, and the warming for irregularly-variable sources does not apply to our target which is a main sequence star. 160683697 ----- Attempting Submission 1 (Wed Jul 13 17:09:42 GMT 2022) ----- HST Phase II Proposal 17113 successfully submitted. Receipt: # 17113-1 ----- Attempting Submission 2 (Fri Aug 19 17:06:37 GMT 2022) ----- ----- Attempting Submission 3 (Fri Sep 02 16:34:05 GMT 2022) ----- For the COS observations, we have selected G130M and WAVECEN=1291 with the use of BOTH the segment A and segment B. To comply with the COS2025 policy, we propose to program the observations into two separated exposures : one with FP-POS=3 and one with FP-POS=4 (exposures 4 and 5, respectively). Simultaneous detection of Mg, C and O to trace dust and ices in exocomets of the young system HD172555 HD 172555 is a young planetary system embedded in a warm gaseous debris disk seen edge-on. A stable gas component and transiting exocomets can be observed in details using absorption spectroscopy. Several variable absorption features identified as due to transiting exocomets have been detected in the optical and UV spectra. HST COS and STIS observations revealed the presence of highly ionized species, ionized carbon and neutral oxygen in the cometary gaseous tails. Nonetheless, the limited wavelegnth coverage of available HST observations of HD172555 precludes from detecting refractory species simultaneusly with volatile elements, which is needed to determine if these star-grazing evaporating bodies are volatile-rich or not. The observations are aimed at probing the dust-to-ice ratio in transiting exocomets of HD172555. This objective can be achieved by capturing exocomet signatures simultaneously in MgII, CII and OI lines with COS/FUV and STIS/NUV spectra of this young star. Magnesium is one of the main constituant of silicate (forsterite, enstatite), while carbon, oxygen and CO are among the main species forming ices in comets. The dust-to-ice ratio will be given by the simultaneous measurement of absorption signatures of these key species. The program is developped into 8 observation sequences that are composed of 2 visits grouped wihtin 1.1 orbit to be executed back-to-back in any order. Each of the two visits of an observation sequence has a duration of one HST orbit. The 1st visit/orbit of each observation sequence is dedicated to the FUV observations with COS. The 2nd visit/orbit of each observation sequence is dedicated to NUV observations with STIS. The eight observation sequences have to be separated by more than two days from one to the other. The last observation sequence (visits #15 and #16) is to be scheduled between June 1st and July 2nd to coincide with TESS observations. For the COS observations, we have selected WAVECEN=1291 with the use of BOTH the segment A and segment B. To comply with the COS2025 policy, we propose to program the observations into two separated exposures : one with FP-POS=3 and one with FP-POS=4 (exposures 4 and 5, respectively). The impact of reduced-gyro operations is believed to be neglegible on the present program, except for the possible consequence to postpone the completion of an 8 observation sequences (~8 "visits") program well beyond the end of Cycle 30, The PI and the Co-PI of the proposal, A. Lecavelier des Etangs and F. Kiefer have long term expertise in both HST data analysis (STIS, ACS, COS) and modeling of exocomets transits. They are co-authors of more than one hundred papers on exoplanets atmospheres and observation of exocomets (including 5 papers in Nature and a Nature paper as first authors on exocomets in Beta Pic : Kiefer, Lecavelier et al. 2014). They are first authors of a dozen of papers directly related to HST observations covering both theoretical and observational aspects of exoplanetary science. They have been PIs of a total of 8 HST programs on exoplanets transit, circumstellar disks and exocomets observations. The team includes experts in HST data analysis (principally in UV) and in modeling of exoplanets atmospheres. Alfred Vidal-Madjar and Paul Strom are experts on HST observations of exocomets.
