Exoplanets can be detected with various observational techniques. Among them, radial
velocity (RV) has the key advantages of revealing the architecture of planetary systems and …

We derive a semianalytic criterion for the presence of chaos in compact, eccentric
multiplanet systems. Beyond a minimum semimajor axis separation, below which the …

Many discovered multiplanet systems are tightly packed. This implies that wide parameter
ranges in masses and orbital elements can be dynamically unstable and ruled out. We …

Planetary systems with multiple giant planets provide important opportunities to study
planetary formation and evolution. The HD 45364 system hosts two giant planets that reside …

Planetary systems exhibiting mean-motion resonances (MMRs) offer unique opportunities to
study the imprint of disk-induced migration on the orbital architectures of planetary systems …

The newest generation of radial velocity spectrographs are impressive instruments that are
capable of making RV measurements with extreme precision (< 30 cm s− 1). The biggest …

As we enter the era of TESS and JWST, instrumentation that can carry out radial velocity
measurements of exoplanet systems is in high demand. We will address this demand by …

The aim of this work is to analyse the orbital dynamics and stability of exoplanetary system in
which two planets are in nearly 3: 2 MMR. We have taken HD 45364 system for our study in …

With the rapid increase in our ability to observe exoplanets and exoplanetary systems over
the past two decades, the amount of data available to planet formation theorists has grown …
