Optical Properties of Organic Haze Analogues in Water-rich Exoplanet Atmospheres Observable with JWST [PDF]

Nature Astronomy (2023), 2023
JWST has begun its scientific mission, which includes the atmospheric characterization of transiting exoplanets. Some of the first exoplanets to be observed by JWST have equilibrium temperatures below 1000 K, which is a regime where photochemical hazes are expected to form.

The Fourier-Kelvin Stellar Interferometer: a low-complexity low-cost space mission for high-resolution astronomy and direct exoplanet detection [PDF]

SPIE Proceedings, 2006
The Fourier-Kelvin Stellar Interferometer (FKSI) is a mission concept for a spacecraft-borne nulling interferometer for high-resolution astronomy and the direct detection of exoplanets and assay of their environments and atmospheres. FKSI is a high angular resolution system operating in the near to midinfrared spectral region and is a scientific and ...

Search for possible exomoons with FAST telescope [PDF]

, 2017
Our knowledge of the Solar System, encourages us to beleive that we might expect exomoons to be present around some of the known exoplanets. With present hardware and existing optical astronomy methods we shall not be able to find exomoons at least 10 ...

Asteroseismology of Exoplanet Host Stars [PDF]

arXiv, 2015
Asteroseismology is among the most powerful observational tools to determine fundamental properties of stars. Space-based photometry has recently enabled the systematic detection of oscillations in exoplanet host stars, allowing a combination of ...

First direct detection of an exoplanet by optical interferometry [PDF]

Astronomy & Astrophysics, 2019
Aims. To date, infrared interferometry at best achieved contrast ratios of a few times 10−4 on bright targets. GRAVITY, with its dual-field mode, is now capable of high contrast observations, enabling the direct observation of exoplanets. We demonstrate the technique on HR 8799, a young planetary system composed of four known giant exoplanets. Methods.

Astronomy from the moon in the next decades: from exoplanets to cosmology in visible light and beyond [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
We look at what astronomy from the Moon might be like over the next few decades. The Moon offers the possibility of installing large telescopes or interferometers with instruments larger than those on orbiting telescopes. We first present examples of ambitious science cases, in particular ideas that cannot be implemented from Earth.

Simultaneous Infrared Observations of the Jovian Auroral Ionosphere and Thermosphere [PDF]

Journal of Geophysical Research: Space Physics, Volume 129, Issue 12, December 2024.
Abstract Simultaneous observations of H3+ ${\mathrm{H}}_{3}^{+}$ and H2 ${\mathrm{H}}_{2}$ in Jupiter's northern infrared aurora were conducted on 02 June 2017 using Keck‐NIRSPEC to produce polar projection maps of H3+ ${\mathrm{H}}_{3}^{+}$ radiance, rotational temperature, column density, and H2 ${\mathrm{H}}_{2}$ radiance. The temperature variations

Exoplanet Detection : A Detailed Analysis [PDF]

arXiv
The exoplanet detection is the most exciting and challenging field of astronomy. The discovery of many exoplanets has revolutionized our understanding of the formation and evolution of planetary systems and has showed new ways to search for extra terrestrial life.
