Tidal interactions shape period ratios in planetary systems with three-body resonant chains
Carolina Charalambous, Jean Teyssandier, Anne-Sophie Libert
These last years several Systems with Tightly packed Inner Planets in the super-Earth mass regime have been discovered harboring chains of resonances. It is generally believed that…
Flat band and Lifschitz transition in long-range ordered supergraphene obtained by Erbium intercalation
A. Zaarour, V. Malesys, J. Teyssandier +10
Dispersionless energy bands are a peculiar property gathering increasing attention for the emergence of novel photonic, magnetic and electronic properties. Here we report the first…
Proximity of exoplanets to first-order mean-motion resonances
Carolina Charalambous, Jean Teyssandier, Anne-Sophie Libert
Planetary formation theories and, more specifically, migration models predict that planets can be captured in mean-motion resonances (MMRs) during the disc phase. The distribution…
Secular chaos in white-dwarf planetary systems: origins of metal pollution and short-period planetary companions
Christopher E. O'Connor, Jean Teyssandier, Dong Lai
Secular oscillations in multi-planet systems can drive chaotic evolution of a small inner body through non-linear resonant perturbations. This "secular chaos" readily pushes the in…
TRAPPIST-1: Dynamical analysis of the transit-timing variations and origin of the resonant chain
Jean Teyssandier, Anne-Sophie Libert, Eric Agol
We analyze solutions drawn from the recently published posterior distribution of the TRAPPIST-1 system, which consists of seven Earth-size planets appearing to be in a resonant cha…
Planetary migration in precessing disks for S-type wide binaries
Arnaud Roisin, Jean Teyssandier, Anne-Sophie Libert
The discovery of numerous circumprimary planets in the last few years has brought to the fore the question of planet formation in binary systems. The significant dynamical influenc…
Transit-Timing Variation Signature of Planet Migration: The Case of K2-24
Jean Teyssandier, Anne-Sophie Libert
The convergent migration of two planets in a gaseous disc can lead to capture in mean motion resonance (MMR). In addition, pairs of planets in or near MMRs are known to produce str…
Pulsed Disc Accretion Driven by Hot Jupiters
Jean Teyssandier, Dong Lai
We present 2D hydrodynamical simulations of hot Jupiters orbiting near the inner edge of protoplanetary discs. We systemically explore how the accretion rate at the inner disc edge…
A Simplified Model for the Secular Dynamics of Eccentric Discs and Applications to Planet-Disc Interactions
Jean Teyssandier, Dong Lai
We develop a simplified model for studying the long-term evolution of giant planets in protoplanetary discs. The model accounts for the eccentricity evolution of the planets and th…
Formation of Hot Jupiters through Secular Chaos and Dynamical Tides
Jean Teyssandier, Dong Lai, Michelle Vick
The population of giant planets on short-period orbits can potentially be explained by some flavours of high-eccentricity migration. In this paper we investigate one such mechanism…
Eccentricity evolution during planet-disc interaction
Enrico Ragusa, Giovanni Rosotti, Jean Teyssandier +3
During the process of planet formation, the planet-discs interactions might excite (or damp) the orbital eccentricity of the planet. In this paper, we present two long ($t\sim 3\ti…
Secular evolution of eccentricity in protoplanetary discs with gap-opening planets
Jean Teyssandier, Gordon I. Ogilvie
We explore the evolution of the eccentricity of an accretion disc perturbed by an embedded planet whose mass is sufficient to open a large gap in the disc. Various methods for repr…
The origin of the eccentricity of the hot Jupiter in CI Tau
Giovanni P. Rosotti, Richard A. Booth, Cathie J. Clarke +3
Following the recent discovery of the first radial velocity planet in a star still possessing a protoplanetary disc (CI Tau), we examine the origin of the planet's eccentricity (e…
Growth of eccentric modes in disc-planet interactions
Jean Teyssandier, Gordon I. Ogilvie
We formulate a set of linear equations that describe the behaviour of small eccentricities in a protoplanetary system consisting of a gaseous disc and a planet. Eccentricity propag…
Torque on an exoplanet from an anisotropic evaporative wind
Jean Teyssandier, James E. Owen, Fred C. Adams +1
Winds from short-period Earth and Neptune mass exoplanets, driven by high energy radiation from a young star, may evaporate a significant fraction of a planet's mass. If the moment…
Evolution of eccentricity and orbital inclination of migrating planets in 2:1 mean motion resonance
Jean Teyssandier, Caroline Terquem
We determine, analytically and numerically, the conditions needed for a system of two migrating planets trapped in a 2:1 mean motion resonance to enter an inclination-type resonanc…
Extreme orbital evolution from hierarchical secular coupling of two giant planets
Jean Teyssandier, Smadar Naoz, Ian M. Lizarraga +1
Observations of exoplanets over the last two decades have revealed a new class of Jupiter-size planets with orbital periods of a few days, the so-called "hot Jupiters". Recent meas…
Orbital evolution of a planet on an inclined orbit interacting with a disc
Jean Teyssandier, Caroline Terquem, John C. B. Papaloizou
We study the dynamics of a planet on an orbit inclined with respect to a disc. If the initial inclination of the orbit is larger than some critical value, the gravitational force e…
Secular Dynamics in Hierarchical Three-Body Systems
Smadar Naoz, Will M. Farr, Yoram Lithwick +2
The secular approximation for the evolution of hierarchical triple configurations has proven to be very useful in many astrophysical contexts, from planetary to triple-star systems…
Hot Jupiters from Secular Planet--Planet Interactions
Smadar Naoz, Will M. Farr, Yoram Lithwick +2
About 25 per cent of `hot Jupiters' (extrasolar Jovian-mass planets with close-in orbits) are actually orbiting counter to the spin direction of the star. Perturbations from a dist…
