Do you want it to do something new? +We propose improved coverage of the WFIRST microlensing field located +approximately at the Galactic coordinates l = 1 deg, b = -1 deg. +First, we propose observations with 15 minute cadence simultaneously with +the WFIRST observations, i.e., during each of six 72-day WFIRST exoplanet +campaigns. The campaigns are in spring and fall (3 starting in fall 2026 and +3 starting in 2029) when the field is visible for a short time each night. +Second, we propose additional single visit each night outside +the WFIRST campaigns. These observations should start a year before and end +a year after the WFIRST microlensing survey. + +The WFIRST microlensing field is approximately defined by a polygon in (l,b) +coordinates: +(-0.5, -2.04), (-0.5, -1.24), (0.73, -1.24), (0.73, -0.46), (1.62, -0.46), (1.62, -2.04). +The field can be fully covered by a single LSST pointing. We request +observations in *z* or *i* bands because of high extinction. ## Science Motivation -Write a few sentences about why you want to make this change. Which -science projects will benefit, do you expect? +The simultaneous observations of a planetary microlensing event from +the ground and a satellite allow direct measurement of the planet mass +and distance thanks to the microlensing parallax effect. +The combination of the WFIRST and the LSST observations is a unique +opportunity to measure the masses of the free-floating planets. +We request observations with cadence matched to WFIRST and to be taken in +the red filters to reduce the impact of interstellar extinction. + +The second part of the proposed observations will allow better +characterization of some of the WFIRST events, most importantly the ones +that show planetary signals during the WFIRST campaigns, +but planet host peak is not covered by the WFIRST. In the extreme cases, +the LSST observations will allow detection of host stars for planets +that seem free-floating based on the WFIRST data alone. The LSST observations +will also prompt higher-cadence observations on smaller telescopes +for events showing particularly interesting features. + +WFIRST will image the microlensing field around 15,000 times with +HST-like quality. This wealth of data will allow multiple additional +investigations for which LSST coverage may be useful: +accurate measurements of parallaxes and proper motions, +studies of variable stars, and investigation of Solar System bodies. + diff --git a/opsim/README.md b/opsim/README.md index 035e08a..02508d9 100644 --- a/opsim/README.md +++ b/opsim/README.md @@ -25,7 +25,7 @@ NEO optimized runs | SS SC | [#120](https://github.com/LSSTScienceCollaborations [Normal Plane](https://github.com/LSSTScienceCollaborations/ObservingStrategy/blob/master/opsim/Proposal_GP.md) | [Strader](https://github.com/caprastro) (for SMWLV) | [#162](https://github.com/LSSTScienceCollaborations/ObservingStrategy/issues/162) | Do Galactic Plane with normal WFD cadence [Rolling Cadence Optimized for SN Cosmology](https://github.com/LSSTScienceCollaborations/ObservingStrategy/blob/master/opsim/Proposal_SN.md) | [Jeonghee Rho ](https://github.com/jhrlsst) [and SN Cosmology Team] | [#159](https://github.com/LSSTScienceCollaborations/ObservingStrategy/issues/159) | Modified Rolling Cadence for densely populated SN light curves [Coordinate with Euclid](https://github.com/LSSTScienceCollaborations/ObservingStrategy/blob/master/opsim/Proposal_Euclid.md) | [Andrew Connolly](https://github.com/connolly) and Tony Tyson | [#530](https://github.com/LSSTScienceCollaborations/ObservingStrategy/issues/530) | An extension of the northern footprint of the Survey to Dec < +30 with no pairs of visits - [Coordination with WFIRST microlensing](https://github.com/LSSTScienceCollaborations/ObservingStrategy/blob/master/opsim/Proposal_WFIRST-micro.md) | [Poleski](https://github.com/rpoleski), [Penny](https://github.com/mtpenny) | ... | Add special (micro-)survey to cover WFIRST microlensing field + [Coordination with WFIRST: exoplanet demographics from microlensing experiment](https://github.com/LSSTScienceCollaborations/ObservingStrategy/blob/master/opsim/Proposal_WFIRST-micro.md) | [Poleski](https://github.com/rpoleski), [Penny](https://github.com/mtpenny) | [#687](https://github.com/LSSTScienceCollaborations/ObservingStrategy/issues/687) | Add special (micro-)survey to cover WFIRST microlensing field [Single filter Northern Ecliptic Spur](Proposal_single_filter_northern_ecliptic_spur.md) | [mschwamb](https://github.com/mschwamb)| ... | Observe the Northern Ecliptic Spur in a single filter (r or g) [...](https://github.com/LSSTScienceCollaborations/ObservingStrategy/blob/master/opsim/) | [...](https://github.com/) | [...](https://github.com/LSSTScienceCollaborations/ObservingStrategy/issues/) Here's the [proposal template](https://github.com/LSSTScienceCollaborations/ObservingStrategy/blob/master/opsim/Proposal_Template.md)
