Improved Orbital Parameters and Transit Monitoring for HD 156846b [PDF]

, 2011
HD 156846b is a Jovian planet in a highly eccentric orbit (e = 0.85) with a period of 359.55 days. The pericenter passage at a distance of 0.16 AU is nearly aligned to our line of sight, offering an enhanced transit probability of 5.4% and a potentially ...

Population dynamics of stubby root nematodes (Trichodorus and Paratrichodorus spp.) associated with ‘Docking disorder’ of sugar beet (Beta vulgaris L.), in field rotations with cover crops in East England

Annals of Applied Biology, EarlyView.
This study evaluated the population dynamics of stubby root nematodes (SRN) in field rotations with cover crops and the subsequent effect of this rotation on sugar beet quality and quantity attributes. It was clear that the SRN densities under field conditions are influenced by multiple factors, such as the type of cover crops grown, soil disturbance ...

The TESS-Keck Survey. VII. A Superdense Sub-Neptune Orbiting TOI-1824

The Astronomical Journal
We confirm a massive sub-Neptune-sized planet on a P = 22.8 days orbit around the star TOI-1824 ( T _eff = 5200 K, V = 9.7 mag). TESS first identified TOI-1824 b (formerly TOI-1824.01) as an object of interest in 2020 April after two transits in Sector ...

Precise Photometry and Spectroscopy of Transits

, 2007
A planetary transit produces both a photometric signal and a spectroscopic signal. Precise observations of the transit light curve reveal the planetary radius and allow a search for timing anomalies caused by satellites or additional planets. Precise measurements of the stellar Doppler shift throughout a transit (the Rossiter-McLaughlin effect) place a

Kepler Observations of Transiting Hot Compact Objects

, 2010
Kepler photometry has revealed two unusual transiting companions orbiting an early A-star and a late B-star. In both cases the occultation of the companion is deeper than the transit. The occultation and transit with follow-up optical spectroscopy reveal

TOI-2015 b: A Warm Neptune with Transit Timing Variations Orbiting an Active Mid-type M Dwarf

The Astronomical Journal
We report the discovery of a close-in ( P _orb = 3.349 days) warm Neptune with clear transit timing variations (TTVs) orbiting the nearby ( d = 47.3 pc) active M4 star, TOI-2015.

New MOST Photometry of the 55 Cancri System [PDF]

, 2013
Since the discovery of its transiting nature, the super-Earth 55 Cnc e has become one of the most enthusiastically studied exoplanets, having been observed spectroscopically and photometrically, in the ultraviolet, optical and infrared regimes. To this rapidly growing data set, we contribute 42 days of new, nearly continuous MOST photometry of the 55 ...

Single‐cell genomics meets systems neuroscience: Insights from mapping the brain circuitry of stress

Journal of Neuroendocrinology, EarlyView.
Abstract Responses to external and internal dangers is essential for survival and homeostatic regulation. Hypothalamic corticotropin‐releasing hormone neurons (CRHNs) play a pivotal role in regulating neuroendocrine responses to fear and stress.

Exoplanet Detection Using AI in Transit Photometry

, 2023
This study delves into the techniques and results of detecting exoplanets using transit photometry, leveraging data obtained from the Kepler Space Telescope. The research aims to shed light on both manual and automated approaches to exoplanet detection, with a specific emphasis on employing the folding technique to identify recurring patterns in light ...

Accurate and Efficient Photoeccentric Transit Modeling

The Astronomical Journal, 2023
A planet’s orbital eccentricity is fundamental to understanding the present dynamical state of a system and is a relic of its formation history. There is high scientific value in measuring the eccentricities of Kepler and Transiting Exoplanet Survey ...
