PI: Dr. Peter J. Wheatley The University of Warwick Y CoI: Dr. David Ehrenreich Observatoire de Geneve Y CoI: Dr. Alain Lecavelier des Etangs CNRS, Institut d'Astrophysique de Paris N CoI: Dr. Kevin Briggs Eidgenossiche Technische Hochschule (ETH) N ------------------------------------------------------------------------------------ Abstract HST observations show that two of the brightest transiting exoplanets are evaporating (HD209458b & HD189733b) and models suggest that the evolution of close-in planets may be dominated by this mass loss. It is believed that the evaporation is driven by X-ray irradiation of the planet by its parent star, but a lack of simultaneous measurements of irradiation and evaporation prevents a meaningful test of this model. We propose simultaneous XMM-Newton and HST observations of three transits of the brightest X-ray source, HD189733, in order to test the paradigm of X-ray driven evaporation and make a direct measurement of the efficiency of exoplanet evaporation. ------------------------------------------------------------------------------------ Observations Description ------------------------ This program consists in 3 visits of 3 orbits. In each visit, we will observe the transit of an exoplanet in front of its parent star, which happens every 2.22 days and lasts for about 2h. Thus, each visit will completely cover the transit. The timing requirements are set as phase constraints on the first acquisition (ACQ) exposure of the first orbit of each visit. The given phase is specified so that the first science exposure is entirely performed before the transit, the second science exposure is done during the transit, and the last exposure entirely after the transit. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- These observations should be carried on together with the XMM-Newton observations. HST and XMM should observe the same transits, but they do not have the same timing requirements for a transit (XMM constraints are typically looser than for HST). 12920( 9) - 06-Sep-2013 15:45:17 - [ 2] The XMM visibility is typically for 36h every two days for around 6 weeks twice per year. The next XMM windows are: - 2012-10-05 to 2012-11-25 - 2013-04-01 to 2013-05-24 We realize that the timing constraints required for each instrument can make the observation difficult to schedule: if this is the case, we can propose to work with our program coordinator to relax some of these constraints to allow better schedulability. ------------------------------------------------------------------------------------ 12920( 9) - 06-Sep-2013 15:45:17 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 HD-189733 STAR, EXTRA-SOLAR RA=20H00M43.7100S +/- 0.1", J2000 V = -2.7 V = 7.65 PLANET, EXTRA-SOLAR DEC=+22D42'39.06" +/- 0.1" PLANETARY SYSTEM, K V-IV Reference Frame: ICRS Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2000 -1.5465808188484117E-4 -0.2514 0.051 ------------------------------------------------------------------------------------------------------------------------------------ 12920( 9) - 06-Sep-2013 15:45:17 - [ 4] Visit: 01 Visit Requirements: BETWEEN 2013.129:22:45 AND 2013.130:05:00 On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 HD-189733 STIS/CCD ACQ F28X50OII MIRROR 1 2 S (2 S) SEQ 1-3 NON-INT ------------------------------------------------------------------------------------------------------------------------------------ 2 HD-189733 STIS/CCD ACQ/PEA 52X0.05 G430L 4300 1 1 S (1 S) K ------------------------------------------------------------------------------------------------------------------------------------ 3 HD-189733 STIS/FUV TIME-TA 52X0.1 G140M 1222 BUFFER-TIME=2000 1 1385 S -MAMA G see below (1385 S) ------------------------------------------------------------------------------------------------------------------------------------ 4 HD-189733 STIS/FUV TIME-TA 52X0.1 G140M 1222 BUFFER-TIME=2000 1 2181 S SEQ 4 NON-INT -MAMA G see below (2933 S) ------------------------------------------------------------------------------------------------------------------------------------ 5 HD-189733 STIS/FUV TIME-TA 52X0.1 G140M 1222 BUFFER-TIME=2000 1 2181 S SEQ 5 NON-INT -MAMA G see below (2933 S) ------------------------------------------------------------------------------------------------------------------------------------ 6 HD-189733 STIS/FUV TIME-TA 52X0.1 G140M 1222 BUFFER-TIME=2000 1 2181 S SEQ 6 NON-INT -MAMA G see below (2933 S) ------------------------------------------------------------------------------------------------------------------------------------ Sub Exposures ------------------------------------------------------------------------------------------------------------------------------------ Target | Exp |Instr | Oper. | Aper |Spectral|Cent.|Primary |Secondary |Iteration |CR-SPLIT |Orbit |Duration Name | Num |Config | Mode | or FOV |Element |Wave.|Pattern Pos |Pattern Pos |Num |Num |Number | ------------------------------------------------------------------------------------------------------------------------------------ HD-189733 1 STIS/CCD ACQ F28X50OI MIRROR none none none none 1 N/A I HD-189733 2 STIS/CCD ACQ/PEA 52X0.05 G430L 4300 none none none none 1 N/A K HD-189733 3 STIS/FUV TIME-TA 52X0.1 G140M 1222 none none none none 1 1385.0 S -MAMA G HD-189733 4 STIS/FUV TIME-TA 52X0.1 G140M 1222 none none none none 2 2933.0 S -MAMA G HD-189733 5 STIS/FUV TIME-TA 52X0.1 G140M 1222 none none none none 3 2933.0 S -MAMA G HD-189733 6 STIS/FUV TIME-TA 52X0.1 G140M 1222 none none none none 4 2933.0 S -MAMA G 12920( 9) - 06-Sep-2013 15:45:17 - [ 5] Visit: 02 Visit Requirements: Period 2.2185757 D AND ZERO-PHASE HJD2454279.43671 On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 HD-189733 STIS/CCD ACQ F28X50OII MIRROR 1 2 S (2 S) PHASE 0.930 TO 0.965;
