Transiting Exoplanet Monitoring Project (TEMP). III. On the Relocation of the Kepler-9~b Transit

Songhu Wang, Dong-Hong Wu, Brett C. Addison +24

The Kepler-9 system harbors three known transiting planets. The system holds significant interest for several reasons. First, the outer two planets exhibit a period ratio that is c…

Searching for the Transit of the Earth--mass exoplanet Proxima~Centauri~b in Antarctica: Preliminary Result

Hui-Gen Liu, Peng Jiang, Xingxing Huang +21

Proxima Centauri is known as the closest star from the Sun. Recently, radial velocity observations revealed the existence of an Earth-mass planet around it. With an orbital period…

OGLE-2016-BLG-1190Lb: First Spitzer Bulge Planet Lies Near the Planet/Brown-Dwarf Boundary

Y. -H. Ryu, J. C. Yee, A. Udalski +106

We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two…

Feedback-limited Accretion: Variable Luminosity from Growing Planets

Matías Gárate, Jorge Cuadra, Matias Montesinos +1

Planets form in discs of gas and dust around stars, and continue to grow by accretion of disc material while available. Massive planets clear a gap in their protoplanetary disc, bu…

OGLE-2016-BLG-0613LABb: A Microlensing Planet in a Binary System

C. Han, A. Udalski, A. Gould +37

We present the analysis of OGLE-2016-BLG-0613, for which the lensing light curve appears to be that of a typical binary-lens event with two caustic spikes but with a discontinuous…

RoboTAP - target priorities for robotic microlensing observations

M. Hundertmark, R. A. Street, Y. Tsapras +21

Context. The ability to automatically select scientifically-important transient events from an alert stream of many such events, and to conduct follow-up observations in response,…

Clearing residual planetesimals by sweeping secular resonances in transitional disks: a lone-planet scenario for the wide gaps in debris disks around Vega and Fomalhaut

Xiaochen Zheng, Douglas N. C. Lin, M. B. N. Kouwenhoven +2

Extended gaps in the debris disks of both Vega and Fomalhaut have been observed. These structures have been attributed to tidal perturbations by multiple super-Jupiter gas giant pl…

Stability of Multiplanetary Systems in Star Clusters

Maxwell Xu Cai, M. B. N. Kouwenhoven, Simon F. Portegies Zwart +1

Most stars form in star clusters and stellar associated. To understand the roles of star cluster environments in shaping the dynamical evolution of planetary systems, we carry out…

LAMOST telescope reveals that Neptunian cousins of hot Jupiters are mostly single offspring of stars that are rich in heavy elements

Subo Dong, Ji-Wei Xie, Ji-Lin Zhou +2

We discover a population of short-period, Neptune-size planets sharing key similarities with hot Jupiters: both populations are preferentially hosted by metal-rich stars, and both…

Transiting Exoplanet Monitoring Project (TEMP). II. Refined System Parameters and Transit Timing Analysis of HAT-P-33b

Y. -H. Wang, S. Wang, H. -G. Liu +19

We present ten -band photometric observations of eight different transits of the hot Jupiter HAT-P-33b, which has been targeted by our Transiting Exoplanet Monitoring Project (T…

MOA-2016-BLG-227Lb: A Massive Planet Characterized by Combining Lightcurve Analysis and Keck AO Imaging

Naoki Koshimoto, Yossi Shvartzvald, David Bennett +55

We report the discovery of a microlensing planet --- MOA-2016-BLG-227Lb --- with a large planet/host mass ratio of . This event was located near the …

Dynamical rearrangement of super-Earths during disk dispersal I. Outline of the magnetospheric rebound model

Beibei Liu, Chris W. Ormel, Douglas N. C. Lin

The Kepler mission has discovered that multiple close-in super-Earth planets are common around solar-type stars, but their period ratios do not show strong pile-ups near mean motio…
