Six months of multiwavelength follow-up of the tidal disruption candidate asassn-14li and implied tde rates from asas-sn
We present ground-based and Swift photometric and spectroscopic observations of the candidate tidal disruption event (TDE) ASASSN-14li, found at the center of PGC043234 (d ' 90 Mpc) by the All-SkyExpand
ASASSN-15oi: a rapidly evolving, luminous tidal disruption event at 216 Mpc
We present ground-based and Swift photometric and spectroscopic observations of the tidal disruption event (TDE) ASASSN-15oi, discovered at the center of 2MASX J20390918-3045201 ($d\simeq216$ Mpc) byExpand

TLDR
The eccentricity distributions of an unprecedented large and homogeneous sample of 698 Kepler planets are derived and a dichotomy in eccentricities is discovered: the systems with single transiting planets, which make up half of the sample, have a large mean eccentricity, whereas the multiples are on nearly circular orbits.

ASASSN-15lh: A highly super-luminous supernova
TLDR
The most luminous supernova yet found was glimpsed in an unusual host galaxy, and has several major features characteristic of the hydrogen-poor super-luminous supernovae (SLSNe-I), whose energy sources and progenitors are currently poorly understood. Expand
The All-Sky Automated Survey for Supernovae (ASAS-SN) Light Curve Server v1.0
The All-Sky Automated Survey for Supernovae (ASAS-SN) is working towards imaging the entire visible sky every night to a depth of V~17 mag. The present data covers the sky and spans ~2-5~years withExpand
Long-term cycling of Kozai-Lidov cycles: extreme eccentricities and inclinations excited by a distant eccentric perturber.
TLDR
The very long-term evolution of the hierarchical restricted three-body problem is calculated analytically for high inclinations by averaging for the first time the double averaged secular equations of motion over the Kozai-Lidov Cycles and finding a new constant of the motion. Expand
THE STATISTICS OF MULTI-PLANET SYSTEMS
We describe statistical methods for measuring the exoplanet multiplicity function (the fraction of host stars containing a given number of planets) and inclination distribution from transit andExpand
FREQUENCY OF SOLAR-LIKE SYSTEMS AND OF ICE AND GAS GIANTS BEYOND THE SNOW LINE FROM HIGH-MAGNIFICATION MICROLENSING EVENTS IN 2005-2008
We present the first measurement of the planet frequency beyond the "snow line," for the planet-to-star mass-ratio interval –4.5 200) microlensing events during 2005-2008. The sampled host stars haveExpand
About 30% of Sun-like Stars Have Kepler-like Planetary Systems: A Study of their Intrinsic Architecture
We constrain the intrinsic architecture of Kepler planetary systems by modeling the observed multiplicities of the transiting planets (tranets) and their transit timing variations (TTVs). We robustlyExpand
Microlens OGLE-2005-BLG-169 Implies That Cool Neptune-like Planets Are Common
We detect a Neptune mass ratio (q 8 ? 10-5) planetary companion to the lens star in the extremely high magnification (A ~ 800) microlensing event OGLE-2005-BLG-169. If the parent is a main-sequenceExpand
