The nature of the progenitor and mass loss remains relatively unknown. Shock interaction with the dense CSM can often result in significant UV emission for several years post-explosion, thereby probing the CSM characteristics, progenitor mass loss history and, ultimately, the progenitor itself. The Type IIn SN 2005ip proves to be one of the most interesting and well-studied targets within this subclass. Compared to all other supernovae, SN 2005ip is the most luminous for its age. Now more than 11 years post-explosion, the SN has released >10^51 erg throughout its lifetime as the forward shock continues to collide with a dense CSM. Here we propose HST/STIS-MAMA UV observations of SN 2005ip to investigate the massive CSM. When accounting for the shock travel time, these observations will probe material lost from the progenitor more than 1000 years prior to the explosion. We already have a single HST/STIS spectrum of SN 2005ip from 2014, which was obtained while the shock was still within a higher mass regime. With just 5 orbits, a second spectrum will allow us to directly trace the evolution of the CSM and produce new constraints on the pre-SN mass-loss history. Coinciding with Cycle 24's UV Initiative, this program offers new insight regarding both the progenitor and explosion characteristics of the SN IIn subclass. ------------------------------------------------------------------------------------ Observations Description ------------------------ We propose to obtain a single STIS-MAMA spectrum of SN 2005ip in both the G140 and G230L bandpasses. The goal is to detect UV signatures of CSM interaction to (1) constrain the CSM characteristics, including the geometry and composition, and (2) confirm emission from CSM interaction as the heating source in the warm-dust model presented by Fox et al. (2011). We choose STIS over COS because, while COS is optimized for isolated faint point-sources, STIS offers spatially resolved spectra that exploit the intrinsically high resolution of HST over a large spectral range (accommodating both the C III] 1909 and Mg II 14598( 3) - 21-Jul-2016 16:06:11 - [ 2] 2800 lines). The long slit length will allow us to subtract contamination from zodiacal light, earthshine, the host galaxy, and H II regions. ------------------------------------------------------------------------------------ 14598( 3) - 21-Jul-2016 16:06:11 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 SN-2005IP EXT-STAR, SUPERNOVA, RA=09H32M6.4200S +/- 0.1", J2000 V = 20.5 SUPERNOVA TYPE II DEC=+08D26'44.40" +/- 0.1" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 14598( 3) - 21-Jul-2016 16:06:11 - [ 4] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type STIS-ALONG-SLIT Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 1 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 90.0 Angle_Between_Sides Center_Pattern YES ------------------------------------------------------------------------------------------------------------------------------------ 14598( 3) - 21-Jul-2016 16:06:11 - [ 5] Visit: 01 (STIS-SN2005ip) Visit Requirements: On Hold Comments: Additional Comments: Normal ACQ.
