The Kilodegree Extremely Little Telescope (or KELT) is an astronomical observation system formed by two robotic telescopes that are conducting a survey for transiting exoplanets around bright stars.

2020年1月15日 · An Atlantic Salmon Kelt will display signs of wear and tear after the rigours of spawning. Patches of fungus can be found and ragged or torn fins are also clear signs. When examining the gills you will often find gill maggots. Kelts are likely to be encountered when fishing for Atlantic Salmon from January to late April.

2024年2月29日 · Because KELT-20 is an A dwarf star, it does not possess a convective layer, and as a result it is less likely that it exhibits granulation signatures. Thus, KELT-20 b is ideally amenable to study 3D weather and variability due to interactions between a highly ionised day side and the planetary magnetic field. 5.4 Spin–orbit alignment

2023年11月8日 · We aim to precisely measure the planetary radius and geometric albedo of the ultra-hot Jupiter (UHJ) KELT-20 b as well as the system’s spin-orbit alignment. We obtained optical high-precision transits and occultations of KELT-20 b using CHEOPS observations in conjunction with the simultaneous TESS observations.

KELT-20b’s comparably high planetary geometric albedo corroborates a known trend of strongly irradiated planets being more reflective. Finally, we tentatively detect signs of temporal variability in the occultation depths, which might indicate variable cloud

The comparably high planetary geometric albedo of KELT-20 b corroborates a known trend of strongly irradiated planets being more reflective. Finally, we tentatively detect signs of temporal variability in the occultation depths, which might indicate variable cloud cover advecting onto the planetary day side.

Kelts are usually easily identified as they are in poor condition. Most are usually thin / lanky in appearance with a flat or hollow belly and often with distended vents. The fins (and particularly the tail) may be damaged or torn. If one has a look in the gills they may on the red gill filaments also have gill maggots*

2023年11月6日 · We aim to precisely measure the planetary radius and geometric albedo of the ultra-hot Jupiter (UHJ) KELT-20 b as well as the system's spin-orbit alignment. We obtained optical high-precision transits and occultations of KELT-20 b using CHEOPS observations in conjunction with the simultaneous TESS observations.

CHEOPS observed the KELT-20 system in the consecutive summers of 2021 and 2022. The first set of observations include four secondary eclipses and four primary transits of the planet KELT-20b extended over a period of two months starting from June 25 to September 1, 2021, while the second includes three
