Abstract

Today, more than three thousand exoplanets have been confirmed and other millions waiting to be discovered. In addition to determine their physical and precise orbital parameters of exoplanets atmosphere is of important to characterize. This will allows us to investigate their evolution and eventually to see the possibility for some exoplanets to harbor a living system. By using the TAU code, we undertake simulations of exoplanets transmission spectra in the near infrared in order to retrieve transmission spectral profiles of these exoplanets. The simulations adopted thermal profile as well as absorption cross-section as a wavelength function for each modeled absorber or trace molecule H2O (0.24 – 0.34 microns) and C2H6 (0-20 microns). The computation provide scale height, optical depth, transit depth and absorption spectra of absorber. The peak of the spectra may lead us to determine the abundance of each molecule in the atmosphere. Our result gave scale height 89% compared to existing data, and total number density of H2O is 5.42×1025 m-3 for Jupiter's atmosphere. Subsequently, we make spectral models of some hot Jupiters, including HD 189733b with WASP 12b, and earth-like exoplanets.

Abstract

We present a theoretical model of atmospheric transparencies for tropical region of Indonesia in the framework of developing multi-wavelength astronomical observations. The wavelengths of interest are radio, infrared, and optical domains. Beside science objectives, sky transparencies are needed to determine the corresponding wavelength band to be optimized in the observatory design. A clear sky condition is then assumed in the model and a line-by-line radiative transfer code is used at high spectral resolution.  The results, combined with study on meteorological satellite data, are utilized to provide various information to select the best possible sites for a new astronomical observatory in Indonesia.

Abstract

We present initial studies to search for the best possible sites for an astronomical observatory in Indonesia. Since the country occupies a vast geographical area, in so doing, we analyzed a number of basic atmospheric parameters based on GMS-NOAA meteorological satellite data at a low spatial resolution to identify some interesting feasible locations. The selected parameters are outgoing long wave radiation, temperature, precipitation, relative humidity, precipitable water, and wind profile, mostly available for a period of several decades. The data are averaged over 30 years to obtain a monthly average profile of Indonesian meteorological situation. The results suggest that regions of Nusa Tenggara Timur could offer promising sites and is merit to be explored further.

Abstract

Global meteorological study over Indonesia has identified that Nusa Tenggara Timur is a good candidate for an astronomical site. West Timor, in the eastern region of Nusa Tenggara Timur, is subsequently selected to be surveyed both for topographical and sky quality. The latter is studied theoretically in term of transmittance of tropical atmosphere. This work presents in situ measurement undertaken for Kupang (longitude: 123° 34¢ 4² E, latitude: 10° 10¢ 19² S) to derive the seeing values. The same procedure was also performed for Lembang, West Java (longitude: 107° 36¢ 58² E, latitude: 6° 49¢ 33² S) in order to quantitatively compare the proposing site to the established one. Our result shows that Kupang has about 50% better seeing condition than that of Lembang.

Abstract

Habitable zone in a planetary system is defined as the region around a star where life-supporting planets can exist. Typically it requires the presence of liquid water on the planetary surface. Considering the formation of planetary systems, we investigate how stellar mass affects the probability of terrestrial planets formed within habitable zone. We use our Planetary System Generator code (Yamani, 2007) to generate planetary systems by investigating its sensitivity through several parameters, such as stellar mass, stellar luminosity, and effective temperature. The probability of finding terrestrial planets within the habitable zone of extrasolar planetary system has been then calculated. We selected the exoplanet systems: Gl 581, HD 128311, 55 Cnc, 47 UMa, and Ups And-like to evaluate the presence of planets within their habitable zone.

Abstract

This paper presents a Monte Carlo simulation, using Planetary System Generator, which has been built based on a simple accretion model by Dole (1970) and by considering the present structure of the Solar System. Data of known extrasolar planets have also been taken into account.   It was then applied to generate 47 Ursae Majoris (47UMa)-like planetary systems. The results are subsequently compared to the observed data of 47UMa. The dynamical evolution as well as the stability of the system have been evaluated by using a n-body formalism accounted for in our simulation. The generated system reproduced approximately the observational data and suggests that some other accompanying planets may exist. The orbital evolution is also found to be stable within the current age of the system.

Abstract

The tendency of a person to commit a criminal act of motorcycle theft repeatedly evidenced by the number of recidivists in the crime of motor theft shows that prison is not a good enough solution to overcome crime. Restorative justice is a settlement system created by the Attorney General's Office through Perja Number 15 of 2020 by stopping the prosecution of cases. The problems discussed in this study are 1) How is the application of the concept of restorative justice as the development of the criminal system in Indonesia? 2) How is the settlement of cases at the prosecutorial level against the crime of motor theft by the public prosecutor based on a restorative justice approach? The approach method used is normative juridical and the research specifications are descriptive analytical by analyzing the applicable laws and regulations with facts in the field. Data analysis using qualitative normative methods. The results showed that: 1) The application of the concept of restorative justice, namely prioritizing the return of all circumstances as an alternative to solving criminal cases that are retaliatory (absolute theory) Restorative justice is present as the development of the criminal system in Indonesia, namely a system that emphasizes improvements in losses caused by or related to criminal acts. 2) The settlement of cases at the district attorney's level against the crime of motor theft by the public prosecutor based on the restorative justice approach is carried out by taking into account the general requirements for the application of restorative justice to the prosecutor's environment as Perja No. 15 of 2020.
