Linearity of Structure Kernels in Main-sequence and Subgiant Solar-like Oscillators

open access: yesThe Astrophysical Journal
Seismic structure inversions have been used to study the solar interior for decades. With the high-precision frequencies obtained using data from the Kepler mission, it has now become possible to study other solar-like oscillators using structure ...

New Ultracool Companions to Nearby White Dwarfs

open access: yesThe Astronomical Journal
We conducted a search for new ultracool companions to nearby white dwarfs using multiple methods, including the analysis of colors and examination of images in both the optical and the infrared.

Magnetic topologies of cool stars [PDF]

open access: yes, 2007
Stellar magnetic fields can be investigated using several, very complementary approaches. While conventional spectroscopy is capable of estimating the average magnetic strength of potentially complex field configurations thanks to its low sensitivity to ...

Olivier Chesneau's Work on Low Mass Stars [PDF]

open access: yesEAS Publications Series, 2015
During his too short career, Olivier Chesneau pioneered the study of the circumstellar environments of low mass evolved stars using very high angular resolution techniques. He applied state of the art high angular resolution techniques, such as optical interferometry and adaptive optics imaging, to the the study of a variety of objects, from AGB stars ...

Demographics of M Dwarf Binary Exoplanet Hosts Discovered by TESS

open access: yesThe Astronomical Journal
M dwarfs have become increasingly important in the detection of exoplanets and the study of Earth-sized planets and their habitability. However, 20%–30% of M dwarfs have companions that can impact the formation and evolution of planetary systems.

Comparing the asteroseismic properties of pulsating extremely low-mass pre-white dwarf stars and δ Scuti stars

open access: yesEPJ Web of Conferences, 2017
We present the first results of a detailed comparison between the pulsation properties of pulsating Extremely Low-Mass pre-white dwarf stars (the pre-ELMV variable stars) and δ Scuti stars.

2D dynamics of the radiative core of low mass stars

open access: yesEPJ Web of Conferences, 2017
Understanding the internal rotation of low mass stars all along their evolution is of primary interest when studying their rotational dynamics, internal mixing and magnetic field generation.

The CHARA Array Interferometric Program on the Multiplicity of Classical Be Stars: New Detections and Orbits of Stripped Subdwarf Companions

open access: yesThe Astrophysical Journal
Rapid rotation and nonradial pulsations enable Be stars to build decretion disks, where the characteristic line emission forms. A major but unconstrained fraction of Be stars owe their rapid rotation to mass and angular momentum transfer in a binary. The
