The stellar spin orientation relative to the orbital planes of multiplanet systems is becoming accessible to observations. Here, we analyze and classify different types of spin–orbit evolution in compact multiplanet systems perturbed by an inclined outer companion. Our study is based on classical secular theory, using a vectorial approach developed in a separate paper. When planet–planet perturbations are truncated at the second order in eccentricity and mutual inclination, and the planet… 
Spin-orbit angle in compact planetary systems perturbed by an inclined companion. Application to the 55 Cancri system
Abstract The stellar spin orientation relative to the orbital planes of multiplanet systems are becoming accessible to observations. For example, 55 Cancri is a system composed of 5 planets orbiting
The Dynamics of the Multi-planet System Orbiting Kepler-56
Kepler-56 is a multi-planet system containing two coplanar inner planets that are in orbits misaligned with respect to the spin axis of the host star, and an outer planet. Various mechanisms have
COMPACT PLANETARY SYSTEMS PERTURBED BY AN INCLINED COMPANION. I. VECTORIAL REPRESENTATION OF THE SECULAR MODEL
The non-resonant secular dynamics of compact planetary systems are modeled by a perturbing function that is usually expanded in eccentricity and absolute inclination with respect to the invariant
Inclination dynamics of resonant planets under the influence of an inclined external companion
Recent observations suggest that a large fraction of Kepler super-Earth systems have external giant planet companions (cold Jupiters), which can shape the architecture of the inner planets, in
Outer-planet scattering can gently tilt an inner planetary system
Chaotic dynamics are expected during and after planet formation, and a leading mechanism to explain large eccentricities of gas giant exoplanets is planet-planet gravitational scattering. The same
The Eccentric Kozai-Lidov Effect and Its Applications
The hierarchical triple-body approximation has useful applications to a variety of systems from planetary and stellar scales to supermassive black holes. In this approximation, the energy of each
Nearly polar orbit of the sub-Neptune HD 3167 c
Aims. We present the obliquity measurement, that is, the angle between the normal angle of the orbital plane and the stellar spin axis, of the sub-Neptune planet HD 3167 c, which transits a bright
Teetering stars: resonant excitation of stellar obliquities by hot and warm Jupiters with external companions
Stellar spin-orbit misalignments (obliquities) in hot Jupiter systems have been extensively probed. Such obliquities may reveal clues about hot Jupiter dynamical histories. Common explanations for
The Dynamics of Tightly-packed Planetary Systems in the Presence of an Outer Planet: Case Studies Using Kepler-11 and Kepler-90
We explore the effects of an undetected outer giant planet on the dynamics, observability, and stability of Systems with Tightly-packed Inner Planets (STIPs). We use direct numerical simulations
The Origin of Systems of Tightly Packed Inner Planets with Misaligned, Ultra-short-period Companions
Ultra-short-period planets provide a window into the inner edge of the parameter space occupied by planetary orbits. In one particularly intriguing class of multiplanet systems, the

Tidal evolution of hierarchical and inclined systems
We investigate the dynamical evolution of hierarchical three-body systems under the effect of tides, when the ratio of the orbital semi-major axes is small and the mutual inclination is relatively
Alignment of the stellar spin with the orbits of a three-planet system
TLDR
An analysis of transits of planets over starspots on the Sun-like star Kepler-30 is reported, and it is shown that the orbits of its three planets are aligned with the stellar equator, similar to that of the Solar System, and contrasts with the isolated hot Jupiters.

Many recent observational studies have concluded that planetary systems commonly exist in multiple-star systems. At least ~20% of the known extrasolar planetary systems are associated with one or
SATELLITE DYNAMICS ON THE LAPLACE SURFACE
The orbital dynamics of most planetary satellites is governed by the quadrupole moment from the equatorial bulge of the host planet and the tidal field from the Sun. On the Laplace surface, the
A primordial origin for misalignments between stellar spin axes and planetary orbits
TLDR
It is suggested that in the absence of strong coupling between the angular momentum of the disk and that of the host star, or of sufficient dissipation that acts to realign the stellar spin axis and the planetary orbits, the fraction of planetary systems whose angular momentum vectors will be commensurate with the rate of primordial stellar multiplicity.
Evolution of spin direction of accreting magnetic protostars and spin–orbit misalignment in exoplanetary systems
Recent observations have shown that in many exoplanetary systems the spin axis of the parent star is misaligned with the planet’s orbital axis. These have been used to argue against the scenario that

Planets have been observed in tight binary systems with separations less than 20 AU. A likely formation scenario for such systems involves a dynamical capture, after which high relative inclinations
MULTIPLE-PLANET SCATTERING AND THE ORIGIN OF HOT JUPITERS
Doppler and transit observations of exoplanets show a pile-up of Jupiter-size planets in orbits with a 3 day period. A fraction of these hot Jupiters have retrograde orbits with respect to the parent
Stellar Spin-Orbit Misalignment in a Multiplanet System
TLDR
Astronomy used asteroseismology to measure a large obliquity for Kepler-56, a red giant star hosting two transiting coplanar planets, to show that spin-orbit misalignments are not confined to hot-Jupiter systems.
