Super-Earth of 8 M in a 2.2-day orbit around the K5V star K2-216

Context. Although thousands of exoplanets have been discovered to date, far fewer have been fully characterised, in particular super-Earths. The KESPRINT consortium identified K2-216 as a planetary candidate host star in the K2 space mission Campaign 8 field with a transiting super-Earth. The planet has recently been validated as well. Aims. Our aim was to confirm the detection and derive the main

K2-260 b : A hot Jupiter transiting an F star, and K2-261 b: A warm Saturn around a bright G star

We present the discovery and confirmation of two new transiting giant planets from the Kepler extended mission K2. K2-260 b is a hot Jupiter transiting a V = 12.7 F6V star in K2 Field 13, with a mass and radius of M = 1.39-0.06+0.05 M⊙ and R = 1.69 ± 0.03 R. The planet has an orbital period of P = 2.627 d, and a mass and radius of MP = 1.42-0.32+0.31 MJ and RP = 1.552-0.057+0.048 RJ. This is the f

44 Validated Planets from K2 Campaign 10

We present 44 validated planets from the 10th observing campaign of the NASA K2 mission, as well as high-resolution spectroscopy and speckle imaging follow-up observations. These 44 planets come from an initial set of 72 vetted candidates, which we subjected to a validation process incorporating pixel-level analyses, light curve analyses, observational constraints, and statistical false positive p

HD 89345 : A bright oscillating star hosting a transiting warm Saturn-sized planet observed by K2

We report the discovery and characterization of HD 89345b (K2-234b; EPIC 248777106b), a Saturn-sized planet orbiting a slightly evolved star. HD 89345 is a bright star (V = 9.3 mag) observed by the K2 mission with 1 min time sampling. It exhibits solar-like oscillations. We conducted asteroseismology to determine the parameters of the star, finding themass and radius to be 1.12-0.01+0.04 M⊙ and 1.

Abstract in Thaiชาวจีนจำนวนมากเดินทางเข้ามายังเดลี-เมดานในช่วงศตวรรษที่ 19 ในฐานะแรงงานสัญญาจ้างเพื่อพัฒนาเขตเกษตรกรรมของดัตช์บนเกาะสุมาตราโดยเฉพาะบริเวณตะวันออกของสุมาตราเหนือครอบคลุมพื้นที่ของเดลี เซอดัง (Deli-Serdang) และเมืองเมดาน (Medan) ในปัจจุบัน พื้นที่ดังกล่าวถูกพัฒนาขึ้นให้กลายเป็นพื้นที่เกษตรกรรมสมัยใหม่ มีการเพาะปลูกพืชหลายชนิด โดยพืชเศรษฐกิจที่สำคัญที่สุดในพื้นที่ขณะนั้น คือ ใบยาสูบ ซIn the 19th Century, Deli-Medan received a large number of Chinese migrants. Most of them worked as labourers in Dutch agricultural plantations on the east coast of Sumatra, extending from Deli-Serdang to Medan. The agricultural products, such as tobacco, were intentionally developed and eventually became the most exportedproducts of Sumatra. As these economic activities paved the way for economic

Estimation of dissolved organic carbon from inland waters at a large scale using satellite data and machine learning methods

Dissolved Organic Carbon (DOC) in inland waters plays an essential role in the global carbon cycle and has significant public health effects. Machine learning (ML) together with remote sensing has emerged as a powerful and promising combination to quantify water quality parameters from space. However, inland water sample data for DOC is limited. Hence, little is known about the potential to quanti

Impact of pre-antiretroviral treatment HIV-RNA on time to successful virological suppression and subsequent virological failure - two nationwide, population-based cohort studies

Background: The impact of pre-antiretroviral treatment (ART) HIV-RNA on time to successful virological suppression and subsequent failure in HIV patients remains poorly investigated. Methods: We used the Swedish InfCareHIV database and the Danish HIV Cohort Study to evaluate impact of pre-ART HIV-RNA on primary virological suppression (HIV-RNA < 50copies/ml) and risk of secondary virological failu

A Systematic Review of Heterogeneity in Outcome Definition and Reporting in Localised Renal Cancer

Context: Outcomes in renal cell carcinoma (RCC) are reported inconsistently, with variability in definitions and measurement. Hence, it is difficult to compare intervention effectiveness and synthesise outcomes for systematic reviews and to create clinical practice guidelines. This uncertainty in the evidence makes it difficult to guide patient-clinician decision-making. One solution is a core out

K2-155 : A Bright Metal-poor M Dwarf with Three Transiting Super-Earths

We report on the discovery of three transiting super-Earths around K2-155 (EPIC 210897587), a relatively bright early M dwarf (V = 12.81 mag) observed during Campaign 13 of the NASA K2 mission. To characterize the system and validate the planet candidates, we conducted speckle imaging and high-dispersion optical spectroscopy, including radial velocity measurements. Based on the K2 light curve and

Exoplanets around Low-mass Stars Unveiled by K2

We present the detection and follow-up observations of planetary candidates around low-mass stars observed by the K2 mission. Based on light-curve analysis, adaptive-optics imaging, and optical spectroscopy at low and high resolution (including radial velocity measurements), we validate 16 planets around 12 low-mass stars observed during K2 campaigns 5-10. Among the 16 planets, 12 are newly valida

Three Small Planets Transiting a Hyades Star

We present the discovery of three small planets transiting K2-136 (LP 358 348, EPIC 247589423), a late K dwarf in the Hyades. The planets have orbital periods of 7.9757 ± 0.0011, 17.30681-0.00036+0.00034, and 25.5715-0.0040+0.0038 days, and radii of 1.05 ± 0.16, 3.14 ± 0.36, and 1.55-0.21+0.24 R⊕, respectively. With an age of 600-800 Myr, these planets are some of the smallest and youngest transit

K2-137 b : An Earth-sized planet in a 4.3-h orbit around an M-dwarf

We report the discovery in K2's Campaign 10 of a transiting terrestrial planet in an ultrashort- period orbit around an M3-dwarf. K2-137 b completes an orbit in only 4.3 h, the second shortest orbital period of any known planet, just 4 min longer than that of KOI 1843.03, which also orbits an M-dwarf. Using a combination of archival images, adaptive optics imaging, radial velocity measurements, an

K2-106, a system containing a metal-rich planet and a planet of lower density

Aims. Planets in the mass range from 2 to 15 M⊙ are very diverse. Some of them have low densities, while others are very dense. By measuring the masses and radii, the mean densities, structure, and composition of the planets are constrained. These parameters also give us important information about their formation and evolution, and about possible processes for atmospheric loss. Methods. We determ
