During the RSG phase, a significant amount of mass loss occurs, and depending on the duration can surround the star with dense and extended circumstellar material (CSM). When the star eventually explodes as a CCSN, high energy photons from the shock breakout ionizes the CSM. These ionization features can be used to constrain the properties of the CSM, including metallicity density, and structure, mapping the evolution of the final years of life of the progenitor star. UV observations during the first two weeks after explosion are crucial for detecting these high ionization lines, and are the most sensitive to lower densities and weaker CSM interactions which may occur in lower mass RSG progenitors. The dearth of UV (particularly FUV) observations of Type IIP/L SNe at this phase has left many open-ended questions about the role CSM interaction plays in "normal" Type II SNe, and a disruptive ToO with HST in the UV is crucial to obtaining these important data on a very short timescale. ------------------------------------------------------------------------------------ Observations Description ------------------------ This proposal will be triggered on a very young type II supernova to obtain UV spectroscopy as close to the trigger time as possible. We will work closely with our contact scientist to ensure the safety of the detectors and with our program coordinator to ensure schedulability. Once triggered, the SN will be observed daily for 3 days and then once one week after the last observation. Each visit will consist of a STIS FUV-MAMA G140L observation with the 52x0.2" slit and a STIS NUV-MAMA G230L observation with the 52x0.2" slit 17132( 9) - 14-Dec-2022 14:31:00 - [ 2] I have created a complete set of visits for 3 scenarios: The supernova is faint at first observation (r~17mag rising to 15mag for last visit) The supernova is bright at first observation (r~14mag rising to 12mag for last visit) The supernova is on a bright background or has a nearby source an requires an offset for the TA (r~17mag rising to 15mag for last visit) Each of these scenarios has the same exposure time per observation ------------------------------------------------------------------------------------ 17132( 9) - 14-Dec-2022 14:31:00 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 4 SNII-17 EXT-STAR, SUPERNOVA RA=00H00M0.0000S +/- 1", J2000 V = 17.0 TYPE II DEC=+00D00'0.00" +/- 1" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 2 SNII-OFFSET EXT-STAR, SUPERNOVA RA-OFF=0.2S, DEC-OFF=0.2", FROM J2000 V = 19.0 TYPE II 3 Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 3 REFERENCE-ST EXT-STAR, SUPERNOVA RA=00H00M0.0000S +/- 1", J2000 V = 19.0 AR TYPE II DEC=+00D00'0.00" +/- 1" Reference Frame: ICRS Extended: NO ------------------------------------------------------------------------------------------------------------------------------------ 5 AT2022ACKO EXT-STAR, SUPERNOVA RA=03H19M38.9700S, J2000 V = 16.5 TYPE II DEC=-19D23'42.87" Reference Frame: ICRS Comments: DLT40 discovery.
