During transit, the gas causes spectroscopic absorption signatures that are routinely detected in several systems. The most prolific case is beta Pic, which continuously displays narrow, variable, non-photospheric absorption features superimposed on the much broader stellar lines. The features vary on short timescales (hours) and are seen at optical (e.g. CaII) and UV (e.g. FeII, SiIV) wavelengths. Previous HST observations of beta Pic in the UV showed the presence of AlIII lines in the exocomet gas. The mere existence of AlIII is puzzling as beta Pic is unable to twice photoionise Al. Hydrodynamical models suggest that these highly-ionised species are formed in a shock where compression and thus collisions within the shock surface are sufficient to generate AlIII. This is theorised to occur when the exocomets get sufficiently close to the star (a few stellar radii). We propose to monitor beta Pic to characterise the doppler movement of the AlIII lines and from this directly measure the exocomets' acceleration. This we use to calculate the comet-star distances. The highly ionised species are thought only to be present in the shock fronts of exocomets close to the star. Measuring the distance between the star and the exocomets will allow us to directly test this hypothesis. The observations cover a wavelength range with other species thought to only emerge in shocks. Measuring the transit ingress/egress times of these species will give us the composition of the shock as a function of radial distance. ------------------------------------------------------------------------------------ Observations Description ------------------------ One line summary: We plan to observe exocometary absoprtion events in the beta 17421( 9) - 09-Jul-2024 20:12:01 - [ 2] Pictoris planetary system with STIS and to track these features by monitoring how the Al III absoprtion line varies as a function of time. The AlIII line is the only line capable of unequivocally detecting an exocometary shocks, given that the second most favourable line (SiIV, which we previously analysed) yields results right at the edge of statistical significance. In order to measure the acceleration as accurately as possible and to avoid blended absorption features, we will use the higher resolution and sensitivity of STIS (compared to COS) using the E230H setup giving. Our setup with the central wavelength set at 1763 Ang, will provide a wavelength coverage from 1624 to 1901Ang. This wavelength range includes many very interesting lines, in which GHRS data has shown detections of transiting exocomets. The line list in this wavelength range includes Fe II, Al II, SI, SiII}, CI, and NiII. Due to the brightness of beta Pic (our target), STIS is in addition required to avoid saturating the detector. Due to the brightness of the object we will be observing in ACCUM mode. Justification for visits and orbits: --- To ensure the two main science goals (1. Test the hypothesis that AlII are caused by shocks and 2. Measure the species dependent size of the shock front) are met we deem it necessary to obtain observations on three separate visits. Three visits ensures completely different exocometry absorption signatures and would avoid the possible conclusion that a detections from a single visit is an outlier. We would further avoid the blending of exocometary signatures. We initially wrote two visits, but believe it is more important to have three visits (with less orbits) than 2 visits with more orbits due to the upredictable nature of the exocomet absorption features. This change was also in part motivated by the strong encouragement from STSci to avoid 3+ orbit visits. There will in total be three visits. The two first visits will consist of 3 orbits and the last visit will consist of 4 orbits. ------------------------------------------------------------------------------------ 17421( 9) - 09-Jul-2024 20:12:01 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 BETA-PIC STAR, A4-A9 V-IV, DISK, RA=05H47M17.0953S, J2000 V = 3.86 EXTRA-SOLAR PLANETARY DEC=-51D03'58.15" SYSTEM Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
