Advanced Engineering Materials, EarlyView.Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

HD 119130 b Is Not an “Ultradense” Sub-Neptune
The Astronomical JournalWe present a revised mass measurement for HD 119130 b (aka K2-292 b), a transiting planet ( P = 17 days, R _p = ${2.63}_{-0.10}^{+0.11}$ R _⊕ ) orbiting a chromospherically inactive G dwarf, previously thought to be one of the densest sub-Neptunes known.

Fluid-mechanical structure of a turbulent premixed V flame
Nihon Kikai Gakkai ronbunshu, 2015 The flow field of a turbulent premixed V flame has been closely examined by using a three-color six-beam LDV system. A bi-modal distribution, composed of the velocity fluctuations of both the high velocity mode and the low velocity mode, is observed ...

Long-lived, long-period radial velocity variations in Aldebaran: A planetary companion and stellar activity [PDF]
, 2015 We investigate the nature of the long-period radial velocity variations in Alpha Tau first reported over 20 years ago. We analyzed precise stellar radial velocity measurements for Alpha Tau spanning over 30 years.

High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy
Advanced Engineering Materials, EarlyView.The oxidation behavior of equiatomic CrFeNi MEA is a key issue that determines this material's suitability for high‐temperature application. The understanding of long‐term behavior is even more crucial than short‐term corrosion effects. The alloy is exposed to synthetic air at 1000, 1050, and 1100 °C for 24, 100, and 1000 h and systematically compared ...

Infrared radial velocities of vB 10 [PDF]
Astronomy & Astrophysics, 2009 We present radial velocities of the M8V-type, very low-mass star vB 10 that have been obtained at four different epochs of observations between 2001 and 2008. We use high-resolution (R ~ 20,000) near-infrared (J-band) spectra taken with the NIRSPEC instrument on the Keck II telescope.

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components
Advanced Engineering Materials, EarlyView.This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

The Astronomical JournalWe conduct experiments on both real and synthetic radial velocity (RV) data to quantify the impact that observing cadence, the number of RV observations, and undetected companions all have on the accuracy of small planet mass measurements.

SOAP 2.0: A TOOL TO ESTIMATE THE PHOTOMETRIC AND RADIAL VELOCITY VARIATIONS INDUCED BY STELLAR SPOTS AND PLAGES [PDF]
, 2014 This paper presents SOAP 2.0, a new version of the Spot Oscillation And Planet (SOAP) code that estimates in a simple way the photometric and radial velocity (RV) variations induced by active regions.
