The New Generation Planetary Population Synthesis (NGPPS). VII. Statistical comparison with the HARPS/Coralie survey
Alexandre Emsenhuber, Christoph Mordasini, Michel Mayor +8
We seek to quantify the fidelity with which modern population syntheses reproduce observations in view of their use as predictive tools. We compared synthetic populations from the…
Earth-like planets hosting systems: Architecture and properties
Jeanne Davoult, Yann Alibert, Lokesh Mishra
The discovery of Earth-like planets is a major focus of current planetology research and faces a significant technological challenge. Indeed, when it comes to detecting planets as…
A radius valley between migrated steam worlds and evaporated rocky cores
Remo Burn, Christoph Mordasini, Lokesh Mishra +4
The radius valley (or gap) in the observed distribution of exoplanet radii, which separates smaller super-Earths from larger sub-Neptunes, is a key feature that theoretical models…
A framework for the architecture of exoplanetary systems. I. Four classes of planetary system architecture
Lokesh Mishra, Yann Alibert, Stéphane Udry +1
We present a novel, model-independent framework for studying the architecture of an exoplanetary system at the system level. This framework allows us to characterise, quantify, and…
A framework for the architecture of exoplanetary systems. II. Nature versus nurture: Emergent formation pathways of architecture classes
Lokesh Mishra, Yann Alibert, Stéphane Udry +1
In the first paper of this series, we proposed a model-independent framework for characterising the architecture of planetary systems at the system level. There are four classes of…
Investigating the Feasibility of an Impact-Induced Martian Dichotomy
Harry A. Ballantyne, Martin Jutzi, Gregor J. Golabek +4
A giant impact is commonly thought to explain the dramatic contrast in elevation and crustal thickness between the two hemispheres of Mars known as the "Martian Dichotomy". Initial…
Three low-mass companions around aged stars discovered by TESS
Zitao Lin, Tianjun Gan, Sharon X. Wang +42
We report the discovery of three transiting low-mass companions to aged stars: a brown dwarf (TOI-2336b) and two objects near the hydrogen burning mass limit (TOI-1608b and TOI-252…
An old warm Jupiter orbiting the metal-poor G-dwarf TOI-5542
Nolan Grieves, François Bouchy, Solène Ulmer-Moll +31
We report the discovery of a 1.32 planet orbiting on a 75.12 day period around the G3V Gyr old star TOI-5542 (TIC 4662…
TIC-320687387 B: a long-period eclipsing M-dwarf close to the hydrogen burning limit
Samuel Gill, Solene Ulmer-Moll, Peter J. Wheatley +26
We are using precise radial velocities from CORALIE together with precision photometry from the Next Generation Transit Survey (NGTS) to follow up stars with single-transit events…
Final Report for SAG 22: A Target Star Archive for Exoplanet Science
Natalie R. Hinkel, Joshua Pepper, Christopher C. Stark +33
Present and upcoming NASA missions will be intensively observing a selected, partially overlapping set of stars for exoplanet studies. Key physical and chemical information about t…
The New Generation Planetary Population Synthesis (NGPPS). VI. Introducing KOBE: Kepler Observes Bern Exoplanets. Theoretical perspectives on the architecture of planetary systems: Peas in a pod
Lokesh Mishra, Yann Alibert, Adrien Leleu +5
(abridged) Observations of exoplanets indicate the existence of several correlations in the architecture of planetary systems. Exoplanets within a system tend to be of similar size…
The New Generation Planetary Population Synthesis (NGPPS). V. Predetermination of planet types in global core accretion models
M. Schlecker, D. Pham, R. Burn +6
State-of-the-art planet formation models are now capable of accounting for the full spectrum of known planet types. This comes at the cost of increasing complexity of the models, w…
Theories of Massive Gravity in 2+1 Dimensions
Lokesh Mishra
This thesis is dedicated to the study of theories of massive gravity. The formulation of higher spin gauge field theories, along with a Chern-Simons (CS) like term for fields of hi…
