Abstract:
During the past five years, 6, 7, and 26 transit observations were carried
out for the HAT-P-9b, HAT-P-32b, and HAT-P-36b systems, respectively,
through the Transiting Exoplanet Monitoring Project network. Combined
with the published photometric data and radial-velocity measurements,
our new photometry allows us to revisit the system parameters and search
for additional close-in planetary companions in these hot Jupiter systems.
We measure an updated RP/R*=0.1260±0.0011 for HAT-P-36 system in
the R band, which is 4.5σ larger than the published i-band radius
ratio of 0.1186±0.0012. We also perform a transit timing variation (TTV)
analysis for each system. Because no significant TTVs were found, we
place an upper mass limit on an additional planet for each system.
Description:
A total of six light curves were obtained for the HAT-P-9b system
between 2016 January and 2017 February using the Xinglong Schmidt
Telescope and Xinglong 60 cm Telescope operated by the National
Astronomical Observatories of China. Seven light curves were obtained
for the HAT-P-32b system between 2012 November and 2016 January using
the same two telescopes. For the HAT-P-36b system, we collected a total
of 26 light curves using the aforementioned telescopes as well as the
Chungbuk National University Observatory in Jincheon (CbNUO) 60 cm
Telescope (Kim et al. 2014ApJ...788..134K 2014ApJ...788..134K), which is operated by CbNUOJ
in South Korea. The observations of the HAT-P-36b system span about
six years from 2012 March to 2017 April.
The Xinglong Schmidt Telescope (Zhou et al. 1999PASP..111..909Z 1999PASP..111..909Z,
2001ChJAA...1..372Z 2001ChJAA...1..372Z) is equipped with a 4Kx4K charge-coupled device (CCD).
The field of view (FOV) is 94'x94', and the pixel scale is 1.38"/pixel.
The images were windowed down to 512x512 pixels to reduce the readout time
from 93 s to 12 s. A Johnson/Cousins R-band filter was used for this
telescope during our observations.
The Xinglong 60 cm Telescope used three different CCDs over the course
of our observing program. Before 2014 November, the telescope was equipped
with a 512x512 CCD, with a FOV of 17'x17', a pixel scale of 1.95"/pixel,
and a standard readout time of 3 s. After that, the telescope used a 1Kx1K
CCD, giving a FOV of 17'x17', a pixel scale of 0.99"/pixel, and a readout
time of about 23 s. In 2015 October readout problems led to this CCD being
replaced by a 2Kx2K CCD with a FOV of 36'x36', a pixel scale of 1.06"/pixel,
and a readout time of 6 s. Finally in 2016 June the 1Kx1K CCD was equipped
again and used for the rest of the observing program. All of the
observations for this telescope also used a Johnson/Cousins R-band filter.
The CCD system of the CbNUO 60 cm Telescope was upgraded in 2012/2013.
For the 2012 observations, a 1530x1020 SBIG ST-8XE CCD was used, giving
a FOV of 27'x18', a pixel scale of 1.05"/pixel, and a readout time of
10 s. The 2013 observations used a 4Kx4K SBIG STX-16083 CCD, which had
a FOV of 72'x72', a pixel scale of 1.05"/pixel, and a readout time of
18 s. The 2012 observations were taken with no filter, and the 2013
observations used an R-band filter.
